CARL E. STEWART, Circuit Judge:
Plaintiffs-Appellants Monica Castro for herself and as next friend of R.M.G., a minor child (collectively “Castro”), brought suit against the United States of America (“the Government”) under the Federal Tort Claims Act (FTCA), 28 U.S.C. § 2671 et seq. Castro alleged, inter alia, that the Government’s negligence caused the wrongful deportation of R.M.G., a U.S. citizen. The Government filed a motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(1) or, alternatively, for summary judgment pursuant to Rule 56. The district court held that the Government is protected from suit due to 28 U.S.C. § 2680(a), the discretionary function exception of the FTCA. Subsequently, the district court entered a final judgment dismissing Castro’s tort claims for lack of subject matter jurisdiction and dismissing her constitutional claims as moot. Castro timely appealed.
FACTUAL AND PROCEDURAL BACKGROUND
The pertinent facts in this case are not in dispute. Castro, a United States citizen, moved with her parents from Corpus Christi, Texas to Lubbock, Texas when she was approximately fifteen years old. Around that time, Castro met Omar Gal-lardo, an illegal alien and Mexican national. When Castro was sixteen, she and Gallardo moved together into a trailer near the trailer that Castro’s parents rented. On December 4, 2002, Castro gave birth to her and Gallardo’s daughter, R.M.G. R.M.G., who was born at the University Medical Center in Lubbock, is a citizen of the United States. Castro was seventeen at the time of R.M.G.’s birth.
Castro and Gallardo had a history of arguing with each other, and Castro contends that Gallardo abused her during the course of their relationship, although she informed neither her parents nor law enforcement authorities of this abuse. Castro maintained that Gallardo was a good father to R.M.G., and that he never abused their daughter.
On November 28, 2003, Castro and Gal-lardo got into an argument, and as a result, Castro called and asked her grandparents to come and pick her up. They came the following day, and Castro left the trailer; R.M.G. remained with Gallardo. Immediately thereafter, Castro commenced efforts to recover R.M.G. from Gallardo. Specifically, she contacted the Lubbock County Sheriffs Department, Texas Child Protective Services (“CPS”), and the Lubbock Police Department. The [384]*384agencies told her that since she was married to Gallardo pursuant to a common-law marriage,1 and because Gallardo was the child’s father, Gallardo had as much right to R.M.G. as she did. Further, Castro was told that her issues with Gallardo constituted a civil dispute, and that she would have to hire a private attorney to seek a custody order. CPS did tell Castro that she could fill out an application to start the process for obtaining assistance from CPS, but that the process would take one to two days. Castro did not fill out the application because she said she did not want to wait one to two days.
On December 1, 2003, Castro, along with her aunt, Sophia Rodriguez, went to the Lubbock Border Patrol station to report that Gallardo was an illegal alien. They spoke with Border Patrol Agent Manuel Sanchez, and they told Sanchez that while Gallardo currently had R.M.G., Castro wanted to recover R.M.G. from him.2 Agent Sanchez informed Castro that she needed to get a court order for temporary custody of R.M.G. However, Agent Sanchez said that if Castro was present when Border Patrol apprehended Gallardo and certain of his relatives, who were also illegal aliens, Border Patrol would leave R.M.G. with Castro, since they both were U.S. citizens. However, Castro did not wish to be present when Border Patrol went to the trailer because she was afraid of what Gallardo and his family would do to her. Accordingly, on the morning of December 3, 2003, Castro was not present when Border Patrol Agents arrived at the trailer Castro shared with Gallardo; rather, Castro watched the events unfold from her relatives’ trailer across the street.
Border Patrol took Gallardo, three of his brothers, and his cousin to the Lubbock Border Patrol station. Since Gallardo had R.M.G. with him, R.M.G. was also taken to the station. Gallardo, R.M.G., and Gallar-do’s relatives were all placed in a holding cell at the station.
Shortly thereafter, Castro arrived at the station and requested that her daughter be returned to her. However, Gallardo informed the Border Patrol Agents that Castro had walked out on him and R.M.G. and that he wanted R.M.G. to remain with him. At the direction of Greg Kurupas, who was the agent-in-charge, Agent Sanchez contacted Debbie Perkins-McCall of the Texas Department of Family and Protective Services (“DFPS”) in Lubbock. Since there was no evidence that R.M.G. was abused or neglected, Agent Sanchez was informed that DFPS would not get involved.3 Meanwhile, Border Patrol pro[385]*385cessed Gallardo and his relatives and prepared to repatriate them back to Mexico. While in custody, Gallardo admitted he was in the United States illegally and chose to reinstate an earlier deportation order. The transport to Mexico from Lubbock left at 3:15 p.m. daily, and Border Patrol made plans to send Gallardo and his relatives at that time.
Around 1:30 in the afternoon, Castro and her relatives retained an attorney, Lisa Trevino, in order to obtain a temporary custody order. Trevino drafted the necessary paperwork and proceeded to the courthouse to get a judge’s signature on the order. Trevino told Agent Kurupas that she was working on obtaining a judge’s signature on a temporary custody order; however, the agent told her that the repatriation transport had to leave by 3:15 p.m. By the time the transport left, Trevino had been unable to obtain a judge’s signature. Trevino never filed any documents with the state court regarding the custody of R.M.G., and she did not further pursue a custody order for Castro.
The transport left Lubbock around 3:15 p.m. on December 3, 2003 with Gallardo onboard, along with R.M.G. In September 2006, Gallardo was detained in the Amarillo area on charges of illegal reentry. While he was in custody, Gallardo and Castro came to an agreement whereby R.M.G., who was living in Mexico with Gallardo’s parents, would be returned to the custody of Castro. R.M.G. was returned to Castro’s custody on December 1, 2006.
Castro filed a lawsuit on February 10, 2006, in the United States District Court for the Southern District of Texas on her own behalf and as next friend of her daughter, R.M.G. In her original complaint, Castro sought monetary damages and injunctive relief pursuant to the Fourth, Fifth, and Tenth Amendments of the United States Constitution, as well as claims of negligence, intentional infliction of emotional distress, and false imprisonment against the United States pursuant to the FTCA. The district court dismissed Castro’s constitutional claims for monetary relief, holding that such claims were barred by the doctrine of sovereign immunity. Castro then filed her First Amended Complaint on May 19, 2006. In this complaint, Castro asserted claims for injunc-tive relief under the Fourth and Fifth Amendments of the United States Constitution as well as claims of negligence, intentional infliction of emotional distress, false imprisonment, abuse of process, and assault pursuant to the FTCA. Castro also asserted a claim for injunctive and declaratory relief pursuant to 8 U.S.C. § 1101, et. seq.
On November 14, 2006, the Government filed a motion to dismiss pursuant to Rule 12(b)(1), and in the alternative, motion for summary judgment pursuant to Rule 56. The Government argued, inter alia, that the district court did not have subject matter jurisdiction over Castro’s tort claims because they are barred by the discretionary function exception to the FTCA. On February 9, 2007, the district court granted the Government’s motion to dismiss for lack of subject matter jurisdiction; the court also held that Castro’s claims for relief under the Fourth and Fifth Amendments and her claim for injunctive relief pursuant to 8 U.S.C. § 1101, et. seq. were moot and therefore dismissed them as well. On April 4, 2007, the district court dismissed Castro’s only remaining claim which sought declaratory relief “in the form of determination of the validity of any statute, regulation, policy or other procedure relied on to detain and deport [386]*386Plaintiff R.M.G.” for lack of standing. That same day, the district court entered its final judgment dismissing the action in its entirety with prejudice.
Castro timely filed her notice of appeal. The only issue Castro raises on appeal is whether the district court erred in dismissing her FTCA claims for lack of subject matter jurisdiction.
STANDARD OF REVIEW
“Whether the district court lacked jurisdiction to consider the government’s conduct in this case is a question of law, subject to de novo review by this court.” Buchanan v. United States, 915 F.2d 969, 970 (5th Cir.1990) (citing Baker v. United States, 817 F.2d 560, 562 (9th Cir.1987)). The party asserting jurisdiction bears the burden of proof for a. Federal Rule of Civil Procedure 12(b)(1) motion to dismiss. Ramming v. United States, 281 F.3d 158, 161 (5th Cir.2001). A motion under 12(b)(1) should be granted only if it appears certain that the plaintiff cannot prove a plausible set of facts that establish subject-matter jurisdiction. See Lane v. Halliburton, 529 F.3d 548, 557 (5th Cir.2008) (citing Bell Atl. Corp. v. Twombly, 550 U.S. 544, 127 S.Ct. 1955, 1965, 167 L.Ed.2d 929 (2007)). “[U]nder Rule 12(b)(1), the court may find a plausible set of facts supporting subject matter jurisdiction by considering any of the following: ‘(1) the complaint alone; (2) the complaint supplemented by undisputed facts evidenced in the record; or (3) the complaint supplemented by undisputed facts plus the court’s resolution of disputed facts.’ ” Lane, 529 F.3d at 557 (quoting Barrera-Montenegro v. United States, 74 F.3d 657, 659 (5th Cir.1996) (internal citations omitted)).
DISCUSSION
“As the sovereign, the United States is immune from suit unless, and only to the extent that, it has consented to be sued.” Truman v. United States, 26 F.3d 592, 594 (5th Cir.1994) (citing Fed. Deposit Ins. Corp. v. Meyer, 510 U.S. 471, 114 S.Ct. 996, 127 L.Ed.2d 308 (1994)). Through the FTCA, the United States has consented to suits “for injury or loss of property, or personal injury or death caused by the negligent or wrongful act or omission of any employee of the Government while acting within the scope of his office or employment....” 28 U.S.C. § 1346(b)(1); see also Truman, 26 F.3d at 594 (“Through the enactment of the FTCA, the government has generally waived its sovereign immunity from tort liability for the negligent or wrongful acts or omissions of its agents who act within the scope of their employment.”)
There are a number of statutory exceptions to the FTCA, two of which are relevant to the resolution of this appeal. First, the “intentional tort” exception provides that the FTCA does not apply to “[a]ny claim arising out of assault, battery, false imprisonment, false arrest, malicious prosecution, abuse of process, libel, slander, misrepresentation, deceit, or interference with contract rights.” 28 U.S.C. § 2680(h). However, that same provision also waives sovereign immunity for the intentional torts of law enforcement and investigative officers. Id. (explaining that the FTCA shall apply “to acts or omissions of investigative or law enforcement officers of the United States Government ... [for] any claim arising ... out of assault, battery, false imprisonment, false arrest, abuse of process, or malicious prosecution.”).4
[387]*387The other relevant exception is the “discretionary function” exception, which provides that the United States is not liable for:
Any claim based upon an act or omission of an employee of the Government, exercising due care, in the execution of a statute or regulation, whether or not such statute or regulation be valid, or based upon the exercise or performance or the failure to exercise or perform a discretionary function or duty on the part of a federal agency or an employee of the Government, whether or not the discretion involved be abused.
28 U.S.C. § 2680(a); see also Sutton v. United States, 819 F.2d 1289, 1298 (5th Cir.1987) (“[T]he government is not liable for any claim arising from the exercise of discretion in the performance of governmental functions or duty whether or not the discretion involved be abused.”) (citing Dalehite v. United States, 346 U.S. 15, 33, 73 S.Ct. 956, 97 L.Ed. 1427 (1953) (internal quotation marks omitted)). “The exception only covers acts that are discretionary in nature, acts that ‘involve an element of judgment or choice.’ ” Gaubert, 499 U.S. at 322, 111 S.Ct. 1267 (citing Berkovitz v. United States, 486 U.S. 531, 536, 108 S.Ct. 1954, 100 L.Ed.2d 531 (1988)). In United States v. S.A. Empresa de Viacao Aerea Rio Grandense (Varig Airlines), 467 U.S. 797, 813, 104 S.Ct. 2755, 81 L.Ed.2d 660 (1984), the Supreme Court explained that it is the nature of the conduct and not the status of the government actor that governs whether the exception applies.
In Gaubert, the Supreme Court laid out a two-step test for determining whether the discretionary function exception applies to a federal employee’s act or omission. First, the challenged government action must be “the product of judgment or choice.” Gaubert, 499 U.S. at 322, 111 S.Ct. 1267. This Court has explained:
Under this prong, we determine whether a statute, regulation, or policy mandates a specific course of action. If such a mandate exists, the discretionary function exception does not apply and the claim may move forward. When no mandate exists, however, the governmental action is considered discretionary and the first prong is satisfied.
Garza v. United States, 161 Fed.Appx. 341, 343 (5th Cir.2005) (internal citation omitted). Second, the court must decide whether the complained of judgment or choice “is of the kind that the discretionary function exception was designed to shield” because the purpose of the exception “is to prevent judicial ‘second-guessing’ of legislative and administrative decisions grounded in social, economic, and public policy through the medium of an action in tort.” Gaubert, 499 U.S. at 322-23, 111 S.Ct. 1267 (internal quotation marks and citations omitted). This Court has written that for this prong, “the appropriate inquiry is whether the act in question is susceptible to policy analysis.” Baldassaro v. United States, 64 F.3d 206, 211 (5th Cir.1995) (internal citation omitted).
As already noted, in the proceedings below, the district court granted the Government’s motion to dismiss pursuant to Rule 12(b)(1). While the district court stated that the aforementioned “law enforcement provision” of § 2680(h) applied to Castro’s assault, abuse of process, and false imprisonment claims, the court ultimately concluded that it lacked subject matter jurisdiction because her FTCA claims could not survive the discretionary function exception. The district judge first determined that the first prong of the [388]*388Gaubert test was satisfied because the Border Patrol Agents’ actions were the product of judgment or choice. In reaching that determination, she highlighted that Castro failed to obtain a custody order granting her custody of R.M.G., and because of that, she placed the Agents in a “difficult situation” — namely, they had to either forcibly remove R.M.G. from Gallar-do’s custody even though there was no court order directing them to do so, or let Gallardo continue with possession of R.M.G., even though Gallardo was being repatriated to Mexico. After concluding that there were no statutes, regulations, or policies mandating that the Agents take a certain course of action in this situation5 and rejecting Castro’s argument that the Agents had made an unauthorized custody determination as to R.M.G., the district judge concluded that the Agents “were left to make a difficult decision, one that was a product of judgment or choice.... ” She also held that the Border Patrol Agents’ actions satisfied the second prong of the Gaubert test because their “decision was unequivocally subject to policy analysis, as it involved the use of government resources and necessarily involved a decision as to what the Border Patrol should do with a United States citizen child in the unique circumstances presented by such a case.” See, e.g., Baum v. United States, 986 F.2d 716, 724 (4th Cir.1993) (a decision as to the best allocation or use of resources is “inherently bound up in considerations of economic and political policy, and accordingly is precisely the type of governmental decision that Congress intended to insulate from judicial second-guessing... .”).
On appeal, Castro argues that the district court unduly narrowed the coverage of the FTCA by improperly expanding the scope of the discretionary function exception. She contends that the district court wrongly interpreted and applied the holdings of Gaubert and related precedent, because, while the Border Patrol Agents’ actions were the product of choice or judgment, their actions not only exceeded the scope of their authority, but also violated the federal Constitution. Further, according to Castro, the Agents’ actions lacked any connection to the social or economic policy of the regulatory regime that establishes the authority of the Border Patrol. The Government urges this court to affirm the district court’s determination, contending that the Agents’ actions in this case are clearly covered by the discretionary function exception of the FTCA. It argues that the district court properly applied Gaubert, and that its judgment dismissing Castro’s FTCA claims for lack of subject matter jurisdiction should be affirmed.
We first observe that we agree with the district court that the law enforcement proviso applies to some of Castro’s FTCA claims since Border Patrol Agents are federal law enforcement officers for purposes of the FTCA. See Ysasi v. Rivkind, 856 F.2d 1520, 1524-25 (Fed.Cir.1988) (explaining that Border Patrol Agents are federal law enforcement officers for the purposes of the FTCA). However, we disagree with the lower court’s conclusions regarding the discretionary function exception. Even though an argument can be made that the district court properly analyzed the two Gaubert factors, that court erred by not first considering whether the Border Patrol Agents exceed[389]*389ed the scope of their authority. In Sutton, we explained: “[W]e have not hesitated to conclude that such action does not fall within the discretionary function exception of § 2680(a) when governmental agents exceed the scope of their authority as designated by statute or the Constitution.” 819 F.2d at 1293. This principle of law has been recognized by a majority of other circuits as well. See, e.g., Raz v. United States, 343 F.3d 945, 948 (8th Cir.2003) (“We must also conclude that the FBI’s alleged surveillance activities fall outside the FTCA’s discretionary-function exception because [plaintiff] alleged they were conducted in violation of his First and Fourth Amendment rights.”); Medina v. United States, 259 F.3d 220, 225 (4th Cir.2001) (noting that the starting point of analysis is that “federal officials do not possess discretion to violate constitutional rights or federal statutes”) (quoting United States Fid. & Guar. Co. v. United States, 837 F.2d 116, 120 (3d Cir.1988)); Nurse v. United States, 226 F.3d 996, 1002 (9th Cir.2000) (holding the Constitution limits the discretion of federal officials such that the discretionary function exception will not apply); Prisco v. Talty, 993 F.2d 21, 26 n. 14 (3d Cir.1993) (concluding that the discretionary function exception was inapplicable to an FTCA claim based on conduct that violated plaintiffs constitutional rights); Red Lake Band of Chippewa Indians v. United States, 800 F.2d 1187, 1196 (D.C.Cir.1986) (“A corollary to these principles, and our basis for affirming the district court’s holding on this issue, is that a decision cannot be shielded from liability if the decisionmaker is acting without actual authority.... An employee of the government acting beyond his authority is not exercising the sort of discretion the discretionary function exception was enacted to protect.”); Birnbaum v. United States, 588 F.2d 319, 329 (2d Cir.1978) (“A discretionary function can derive only from properly delegated authority. Authority generally stems from a statute or regulation, or at least from a jurisdictional grant that brings the discretionary function within the competence of the agency. Discretion may be as elastic as a rubber-band, but it, too, has a breaking point. An act that is clearly outside the authority delegated cannot be considered as an abuse of discretion.” (internal quotation marks and citations omitted)); but see Kiiskila v. United States, 466 F.2d 626, 627-28 (7th Cir.1972) (holding that conduct by commanding officer of military base, although “constitutionally repugnant,” fell within the discretionary function exception).
Admittedly, this court and others have been less than clear about where this “scope of authority” analysis fits within the Gaubert factors: arguably some courts have treated it as a prerequisite, see, e.g., Nurse, 226 F.3d at 1001-02, while others have seemingly integrated it into the first Gaubert factor. See, e.g., McElroy v. United States, 861 F.Supp. 585, 593 (W.D.Tex.1994). Nevertheless, it is overwhelmingly clear that, as the First Circuit has written, “courts have read the Supreme Court’s discretionary function cases as denying protection to actions that are unauthorized because they are unconstitutional, proscribed by statute, or exceed the scope of an official’s authority.” Thames Shipyard & Repair Co. v. United States, 350 F.3d 247, 254 (1st Cir.2003) (internal citations omitted). Because the Constitution can limit the discretion of federal officials such that the FTCA’s discretionary function exception will not apply, if the Agents acted in violation of R.M.G.’s constitutional rights, and therefore outside their scope of authority, that conclusion would eclipse the district court’s analysis under the Gaubert framework.
[390]*390We now turn to consider whether Castro sufficiently alleged that the Border Patrol Agents violated the scope of their authority here. In her complaint, Castro states that the Agents violated R.M.G’s Fourth and Fifth Amendment rights when they detained her in immigration custody with Gallardo and his relatives even though they knew she was a U.S. citizen, and that such actions not only went beyond the scope of their authority, but also violated the constitution.6 While it is well-recognized that violations of constitutional mandates are not actionable under the FTCA, see Meyer, 510 U.S. at 478, 114 S.Ct. 996 (“The United States simply has not rendered itself liable under § 1346(b) for constitutional tort claims.”), the occurrence of such a violation would involve the performance of a non-discretionary function for jurisdictional purposes, if the constitutional tort is also cognizable as an intentional tort under state law. As a federal district court explained:
[A] court must determine whether there is a specific and intelligible constitutional mandate that involves or is related to the alleged intentional torts of the accused officer(s). If such a mandate exists, the Court will conclude, for jurisdictional purposes only, that the alleged torts occurred during the performance of a non-discretionary function. Upon reaching such a conclusion, the Court may determine the merits of the section 2680(h) intentional tort claims under the applicable state tort law.
McElroy, 861 F.Supp. at 593-94. As the McElroy court recognized, “[t]he Gaubert test merely instructs the reviewing court to determine whether the alleged conduct ‘involvefs]’ mandatory compliance with a federal statute, regulation, or policy, not whether the statute, regulation, or policy was violated.” Id. at 593 n. 16; see also Garcia v. United States, 896 F.Supp. 467, 475-76 (E.D.Pa.1995) (“Because we cannot at this point preclude the possibility that the inspectors’ conduct was unconstitutional, we cannot hold that the challenged conduct falls within the discretionary function exception.”). Accordingly, the issue before us is whether the complaint and any properly-considered facts could support a finding that the Border Patrol Agents’ alleged conduct exceeded the scope of their statutory or constitutional authority, not determining whether such a violation actually occurred.
We hold that Castro’s complaint does sufficiently allege that the Border Patrol Agents’ actions exceeded the scope of their authority. The Border Patrol, officially called The Bureau of Customs and Border Protection, is an agency of the Department of Homeland Security, and is specifically included as a defined agency subject to the Immigration and Nationality Act of 1953 (“INA”), 8 U.S.C. § 1101 et seq. See 8 C.F.R. § 1.1. Fundamentally, the INA’s scope is limited to regulating the entry of aliens as well as their detention, expulsion/removal, and naturalization. See, e.g., 8 U.S.C. § 1103(a)(1); 8 U.S.C. § 1101(a)(23). Within this statutory grant of authority, Border Patrol Agents have, [391]*391inter alia, broad discretion in making determinations in matters such as the detention, parole, or deportation of foreign nationals illegally present in the United States. See, e.g., 8 U.S.C. § 1226; 8 C.F.R. §§ 236.1-236.7; INS v. Yueh-Shaio Yang, 519 U.S. 26, 30, 117 S.Ct. 350, 136 L.Ed.2d 288 (1996) (explaining the broad INS discretion in determining who, along a class of eligible aliens, may be granted relief from removal). However, the power of Border Patrol Agents to detain U.S. citizens is quite limited. While Border Patrol Agents possess a general arrest authority for crimes committed in their presence, 8 U.S.C. § 1357(a)(5), generally speaking they do not have authority to arrest or detain U.S. citizens. See, e.g., United States v. Brignoni-Ponce, 422 U.S. 873, 884, 95 S.Ct. 2574, 45 L.Ed.2d 607 (1975) (writing that the Fourth Amendment “forbids stopping or detaining persons for questioning about their citizenship on less than a reasonable suspicion that they may be aliens”).
The Government makes two arguments for why the Agents were within their statutory grant of authority. First, it cites 8 C.F.R. § 240.25(b) which states that immigration officials “may attach to the granting of voluntary departure any conditions [they] deem[] necessary to ensure the alien’s timely departure from the United States.... ” The Government contends that this is simply all the Agents did here. Second, it cites 8 U.S.C. § 1103(a)(3) which provides that the Secretary of Homeland Security “shall establish such regulations; prescribe such forms of bond, reports, entries, and other papers; issue such instructions; and perform such other acts as he deems necessary for carrying out his authority under the provisions of this chapter.” The Government then relies on language from Gaubert to make the argument that the Agents’ actions were all planning-level decisions that are covered by the discretionary function exception. See 499 U.S. at 323, 111 S.Ct. 1267 (“Where Congress has delegated the authority to an independent agency or to the Executive Branch to implement the general provisions of a regulatory statute and to issue regulations to that end, there is no doubt that planning-level decisions establishing programs are protected by the discretionary function exception, as is the promulgation of regulations by which the agencies are to carry out the programs.”).
Both of these arguments are unavailing. The Government’s first argument fails because, as Castro highlights, Gallardo was removed in December 2003 pursuant to the reinstatement of a prior order of removal and not by voluntary departure; therefore 8 C.F.R. § 240.25(b) is simply irrelevant. The Government’s second argument is without merit because even though governmental actors have wide discretion to carry out their statutory and regulatory obligations, courts have never interpreted delegated authority so broadly as to infringe upon constitutionally-protected rights and freedoms. See, e.g., Hernandez v. Cremer, 913 F.2d 230, 237 (5th Cir.1990) (explaining that courts should “construe narrowly all [Congressionally-]delegated powers that curtail or dilute [constitutional protections.]” (citing Kent v. Dulles, 357 U.S. 116, 129, 78 S.Ct. 1113, 2 L.Ed.2d 1204 (1958))). The Government’s contention that 8 U.S.C. § 1103(3) could be interpreted so broadly as automatically to override R.M.G.’s Fourth Amendment right from unreasonable seizure or her Fifth Amendment right to due process is simply untenable.
We are cognizant of the challenging circumstances in which Border Patrol Agents undoubtedly often find themselves because of the complexities of immigration enforcement, and we agree with the district court that, particularly in this instance, they [392]*392were faced with a “difficult situation.”7 As such, we emphasize the narrowness of our holding. Had the Border Patrol Agents not known R.M.G.’s citizenship status or if they had doubted Castro’s assertions that R.M.G. was a U.S. citizen, their decision to detain the child with her father would likely not be intertwined with the constitutional strands that are prominent in this appeal of a 12(b)(1) dismissal for lack of subject matter jurisdiction. However, here the Agents concede that they knew R.M.G. was a U.S. citizen.
Castro alleges a plausible set of facts supporting subject matter jurisdiction because based on her complaint, the Border Patrol Agents’ actions in detaining R.M.G. implicate constitutional concerns and, therefore, may have been non-discretionary. We hold that the district court legally erred in concluding that the discretionary function exception to the FTCA deprived it of jurisdiction without first determining whether the Agents’ conduct was outside their scope of authority.8 We remand this case for the district court to consider in the first instance to what extent the alleged constitutional violations are cognizable under Castro’s FTCA claims. We highlight that our holding is limited to the jurisdictional question presented on appeal; nothing we have written should be interpreted to speak to the merits of either Castro’s allegations of constitutional violations or her FTCA claims.
CONCLUSION
For the foregoing reasons, the judgment of the district court as to Castro’s FTCA claims is REVERSED, and this case is REMANDED for proceedings not inconsistent with this opinion.
