BARKETT, Circuit Judge:
Albert Adefemi, a citizen of Nigeria, petitions for review of a decision of the Board of Immigration Appeals, challenging its determination that the Immigration and Naturalization Service (“INS”) presented sufficient evidence to demonstrate that he could be deported on the basis of a firearms offense.
After entering the United States in 1977 without inspection, Adefemi became a lawful temporary resident on August 17, 1987 and a permanent resident on March 20, 1989. In 1993, the INS initiated deportation proceedings on the basis of two theft offenses of which Adefemi was allegedly convicted in 1991. Adefemi did not contest his deportability, applying instead for discretionary relief under section 212(c) of the Immigration and Nationality Act (“INA”), as amended, 8 U.S.C. § 1182(c) (repealed [1271]*12711996). At that time, section 212(c) authorized the Attorney General to determine whether equitable considerations, such as a family in the United States or a negligible criminal record, favored sparing an immigrant the hardship of deportation. Acting on the Attorney General’s authority, the same administrative judges who preside over deportation proceedings would also consider applications for discretionary waivers under section 212(c).
Over the course of seven years, the INS twice amended its charges against Adefe-mi, eventually alleging that he was deport-able on the basis of a 1991 firearms conviction as well as the theft offenses. Adefemi was found deportable on all grounds. An immigration judge (“IJ”) deemed the INS to have established the firearms conviction “by evidence which is clear, convincing and unequivocal.” Oral Decision of the Immigration Judge, Nov. 10, 1999, at 8. The judge then determined that Adefemi was ineligible for a waiver of deportation under Section 212(c) because controlling administrative precedent limited such relief to persons who are deportable for a reason that would also warrant an alien’s “exclusion” prior to admission into the United States. Holding Adefemi’s firearms offense not to have such an analogue in the exclusion context, the court determined that it “must” find Adefemi ineligible for discretionary relief under section 212(c) because of the firearms offense. Id. at 11.
Adefemi appealed and in 2000 was denied relief by the Board of Immigration Appeals (“BIA” or “Board”), which had earlier issued decisions addressing other aspects of the INS’s case in 1997 and 1999. Like the IJ, the Board found that Adefemi was deportable on the basis of the firearms offense and ineligible for section 212(c) relief as a result. Adefemi filed a petition for review with this Court, and a three-judge panel granted his motion for a stay of deportation on March 5, 2001. He now raises a range of claims pertaining to his lengthy administrative proceedings.
DISCUSSION
The upheaval in immigration law effected by two pieces of 1996 legislation, the Antiterrorism and Effective Death Penalty Act (“AEDPA”), Pub. L. No. 104-132, 110 Stat. 1214, and the Illegal Immigration Reform and Immigrant Responsibility Act (“IIRIRA”), Pub. L. No. 104-208,110 Stat. 3009, has raised numerous and ponderous questions regarding both the substantive law to be applied in immigration proceedings and the extent of federal judicial authority to review determinations made by administrative tribunals. One particularly vexing matter has been the extent to which convictions for certain statutorily enumerated crimes operate as complete bars to discretionary relief from deportation. See, e.g., INS v. St. Cyr, 533 U.S. 289, 121 S.Ct. 2271, 150 L.Ed.2d 347 (2001). Although the complexities of this issue have to date bedeviled the course of Adefemi’s administrative proceedings, the parties agreed at oral argument that a remand to allow Adefemi to apply for discretionary relief will be appropriate should we decide he is not deportable on the basis of the asserted firearms offense.1 We [1272]*1272therefore commence with the question of our jurisdiction to hear Adefemi’s challenge to this discrete aspect of the administrative proceedings in his case.
I. JURISDICTION
Because deportation proceedings against Adefemi were commenced before April 1, 1997, and a final deportation order was entered more than thirty days after September 30, 1996, our jurisdiction is governed by former Section 106(a) of the INA, 8 U.S.C. § 1105a (1996), as amended by the transitional rules set forth in Section 309(c) of the IIRIRA (reprinted in 8 U.S.C.A. § 1101 (historical notes)). See Al Najjar v. Ashcroft, 257 F.3d 1262, 1276-77 (11th Cir.), reh’g en banc denied, 275 F.3d-1085 (2001). The jurisdiction of the courts of appeals under IIRIRA is triggered by the entrance of a “final order” of deportation. See IIRIRA, § 309(c)(4)(C) (providing for petition for review to be filed not later than 30 days after date of “final order”); 8 U.S.C. § 1105a(a)(l) (referring to review of “final deportation order”). A deportation order becomes final “upon dismissal of an appeal by the Board.” 8 C.F.R. § 241.31 (2002). Because the Board did not conclusively dismiss Adefe-mi’s appeal until its October 4, 2000 decision, its earlier decisions in 1997 and 1999 were not final orders.2 By filing his petition for review on November 2, 2000, 29 days after the Board dismissed his appeal, Adefemi satisfied the 30-day timely filing requirement set forth in the statute. IIR-IRA, § 309(c)(4)(C).
The transitional rules provide that: there shall be no appeal permitted in the case of an alien who is inadmissible or deportable by reason of having committed a criminal offense covered in section 212(a)(2) or section 241(a)(2)(A)(iii), (B), (C), or (D) of the Immigration and Nationality Act (as in effect as of the date of the enactment of this Act)....
IIRIRA § 309(c)(4)(G). At the time of IIRIRA’s enactment, one of the statutes incorporated by this transitional rule directed as follows:
Any alien who at any time after entry is convicted under any law of purchasing, selling, offering for sale, exchanging, using, owning, possessing, or carrying, or [1273]*1273of attempting or conspiring to purchase, sell, offer for sale, exchange, use, own, possess, or carry, any weapon, part, or accessory which is a firearm or destructive device (as defined in section 921(a) of Title 18) in violation of any law is deportable.
INA § 241(a)(2)(C), 8 U.S.C. § 1251(a)(2)(C) (1996). Hence the transitional rule purports to place strict limits on the judicial review available to aliens who, like Adefemi, have been found deportable because of a firearms offense.
It is by now well established, however, that we retain jurisdiction in such cases to the extent necessary to review whether the statutory prerequisites of Section 309 apply. Farquharson v. U.S. Attorney General, 246 F.3d 1317, 1320 (11th Cir.2001) (citing Lettman v. Reno, 168 F.3d 463, 465 (11th Cir.1999)); cf. Calcano-Martinez v. INS, 533 U.S. 348, 350 n. 2, 121 S.Ct. 2268, 150 L.Ed.2d 392 (2001) (noting government’s concession that “the courts of appeals have the power to hear petitions challenging the factual determinations thought to trigger [a substantially identical] jurisdiction-stripping provision”). We therefore have jurisdiction to determine whether Adefemi is (1) an alien who is (2) deportable (3) by reason of a firearms offense. Farquharson, 246 F.3d at 1320.
The transitional rule set forth in Section 309(c)(4)(G) creates a certain ambiguity as to when an alien is deportable “by reason of a firearms offense.” Whereas the transitional rule refers generally to aliens “de-portable by reason of having committed” a range of crimes, the underlying statute which it incorporates by reference makes aliens “deportable” only when they have been “convicted under any law” of a qualifying firearms offense. We have previously reasoned, in examining comparable immigration provisions structured in the same fashion, that the meaning of the term “deportable” as used in the provision limiting our jurisdiction must be derived from the underlying statute’s specification of how an alien becomes deportable. Fernandez-Bernal v. Attorney General, 257 F.3d 1304, 1308-09 (11th Cir.2001) (construing provisions relating to controlled substance offenses). That is, we have jurisdiction to determine whether Adefemi is deportable because he has been “convicted under any law” of a qualifying firearms offense. 8 U.S.C. § 1251(a)(2)(C).
Our jurisdictional inquiry thus merges with the merits of Adefemi’s challenge, which rests on his assertion that the INS failed to prove a qualifying firearms conviction by sufficient evidence. We therefore proceed to the merits on the understanding that we have jurisdiction to grant relief if the government failed to prove that Adefemi was convicted of a firearms offense.
II. SUFFICIENCY OF EVIDENCE DEMONSTRATING CONVICTION
In the administrative proceedings under review, the INS relied exclusively on a single piece of evidence in support of its charge that Adefemi was deportable on the basis of a firearms conviction. This was a two-sided, preprinted document that would be colloquially termed a traffic “ticket.” On the front appears a uniform citation form used to charge drivers with moving violations. On the reverse is boilerplate language for use in recording several types of action taken in the City Court of Atlanta, such as the receipt of a plea or the imposition of sentence.
The IJ determined that “Respondent waived a trial by jury, pled guilty, and was convicted and directed to pay a fine of $330, [or in] default of such payment be confined for a term of 12 months.” Oral Decision of the Immigration Judge, Nov. 10, 1999, at 3. The Board affirmed, but [1274]*1274unlike the IJ, was silent as to whether Adefemi had pled guilty. In the proceedings before these tribunals, the only evidence presented by the INS was the two-sided document. Although Adefemi raises several- challenges to the Board’s decision, his central contention is that this ticket, the sole piece of evidence against him, was insufficient to demonstrate his deportability on the basis of a firearms conviction. See Petitioner’s Supplemental Brief at 20-26.3
Whether a conviction has been sustained is a question of fact on which we defer to the Board if its determination is “supported by reasonable, substantial, and probative evidence on the record considered as a whole.” 8 U.S.C. § 1105a(a)(4) (repealed 1996) (applicable to this case under IIRIRA § 309(e)(4)(l)(A)). Under this “substantial evidence” standard, we will not reverse the Board’s determination unless “a reasonable factfinder would have to conclude” that no conviction has been proved. See Lorisme v. INS, 129 F.3d 1441, 1445 (11th Cir.1997) (quoting INS v. Elias-Zacarias, 502 U.S. 478, 481, 112 S.Ct. 812, 117 L.Ed.2d 38 (1992)).
Although our own review is deferential, the INS must prove an alien’s deportability by “clear and convincing evidence.” 8 U.S.C. § 1229a(e)(3)(A); Woodby v. INS, 385 U.S. 276, 286, 87 S.Ct. 483, 17 L.Ed.2d 362 (1966) (requiring “clear, unequivocal, and convincing evidence that the facts alleged as grounds for deportation are true”). Under this “intermediate standard” of proof, Adding-ton v. Texas, 441 U.S. 418, 424, 99 S.Ct. 1804, 60 L.Ed.2d 323 (1979), the government bears a “heavy burden.” Berenyi v. District Director, INS, 385 U.S. 630, 636, 87 S.Ct. 666, 17 L.Ed.2d 656 (1967). As a court of review, we are well acquainted with the task of integrating our own deferential review of factual determinations with the heightened burden of proof borne by certain parties to litigation. For example, when a defendant in a criminal case argues on appeal that the evidence was insufficient to convict him, we ask whether a reasonable trier of fact, after viewing the evidence in the fight most favorable to the government, could find that the defendant’s guilt was established beyond a reasonable doubt. See, e.g., United States v. Miles, 290 F.3d 1341, 1355 (11th Cir.), cert. denied, 537 U.S. 1089, 123 S.Ct. 707, 154 L.Ed.2d 634 (2002). Although this standard safeguards the role of the trier of fact, it also assures that “application of the beyond-a-reasonable-doubt standard to the evidence is not irretrievably committed to jury discretion.” Jackson v. Virginia, 443 U.S. 307, 318 n. 10, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).
Here, our approach is of a similar form but different content: we ask whether the BIA could reasonably conclude that the government has shown Adefemi deporta-ble by clear and convincing evidence. Hence we must determine whether the INS’s evidence could justify the elevated degree of confidence corresponding to its intermediate standard of proof.4 The [1275]*1275Board was clearly cognizant of the heightened standard to which the INS is held, concluding its opinion by quoting the Supreme Court’s directive in Woodby, 385 U.S. at 286, 87 S.Ct. 483, that deportability be established by “clear, unequivocal, and convincing evidence.” The Board found this standard satisfied by the two-sided, preprinted form relied upon by the INS as the exclusive evidence of a firearms conviction.
In order to review this determination, we must examine a somewhat inscrutable combination of signatures, stamps, and handwritten marks recorded on this document. We begin with the front side, on which appears a uniform citation form. On a blank space next to the word “Offense,” a handwritten entry states that Adefemi, in violation of Section 16-11-126 of the Georgia Code, “had a 22 cal RG10 in console between seats.” Although Ga. Code Ann. 16-11-126 proscribes the carrying of a range of concealed weapons other than firearms, Adefemi does not contend that a “22 cal RG10” is anything other than a firearm. Hence the citation form, which was signed by an arresting officer, alleges unlawful possession and/or concealment of a firearm.
It is the material contained on the document’s reverse side, however, upon which the BIA focused in finding that the INS had shown Adefemi’s conviction of a firearms offense by clear and convincing evidence. Although the BIA refers to the reverse side as a “criminal court certificate of disposition,” that phrase does not appear anywhere on the copy entered in the record. Near the top of the form appear two identical signatures. Both the first and the last names of the signature appear to begin with the letter “A,” and the remainder of each signature is consistent with the name Albert Adefemi. Since the front side of the document clearly charges Adefemi with an offense, and since Adefe-mi has never argued that the signatures are not his, we will treat them as such. One of the signatures appears to affirm that “On Arraignment, The Defendant Pleads NOT GUILTY,” whereas the other is entered in a section titled “Plea of Guilty and Waiver.” The form provides no means of discerning which of these signatures reflects Adefemi’s actual plea in this case: there is no indication that he amended an initial plea of not guilty to one of guilty, nor has anything been written in a space provided for stating the charge to which Adefemi, if he did enter a guilty plea, in fact admitted. Consistent with this ambiguity, none of three boxes printed next to each of three possible pleas — ■ [1276]*1276guilty, not guilty, and “nolo cont’d” — have been cheeked in a separate section of the form.
Below the sections bearing Adefemi’s signatures is another section titled “Disposition and Sentence,” in which the word “Probation” has been rubber-stamped. Still lower, in a separate section, the number “330.00” has been written on a space for designating a “fine.” The next line appears5 to state that a term of confinement shall be served should payment be defaulted. However, the portion of the form titled “Disposition and Sentence” has been left entirely blank apart from the “Probation” stamp and a second stamp that reads “State Case.” Significantly, nothing has been written in spaces specifically reserved for identifying the “Sentence: Amount Fine/Forfeiture $” and the number of “Days (Months) probated.” The failure of the Atlanta City Court to complete these sections makes it difficult to interpret the meaning of the “Probation” stamp, since the imposition of a probationary sentence would seem to require that a term of probation be set. By the same token, no ready explanation appears for the fact that a fine has been indicated, not on the appropriate line in the “Disposition and Sentence” section, but only in a separate section under an indiscernible heading beginning with the words “Upon Trial, the Defendant.” Unlike the “Disposition and Sentence” portion of the form, no reference is made in this other section to any adjudication of “guilt” or imposition of “sentence.” Instead, the boilerplate printed on the form reads simply, “It is considered, ordered and adjudged that the defendant pay a fine of_dollars and (in defafindiscernible] of such payment) be confined for a term of_(days6/months) in the____ The confinement specified shal[indiscernible] be suspended on payment of the fine and on condition defendant does not again violate the laws of Georgia.”7
In the absence of additional evidence by which the INS might have clarified the meaning of the form, we do not think it may be said that this document, marked in this manner, provides clear and convincing evidence of a firearms conviction. The very ambiguity of the document does make it impossible to say, with absolute certain[1277]*1277ty, that Adefemi was not convicted of a firearms offense. But we think this same ambiguity makes it unreasonable to conclude that the document is clear and convincing evidence of such a conviction. Our conclusion rests on the- highly tenuous nature of any inferences drawn from what is in essence nothing more than the front and back of a traffic ticket.8 While the document does indicate a fine of $330, it fails to specify the basis for this penalty. Nowhere does it explicitly indicate either the fact of conviction or the offense for which any conviction was entered. It likewise fails to indicate whether Adefemi pled guilty or, if he did, the charge to which he admitted.
Even were we to assume that the clerical stamp reading “Probation” and the reference to a fine are clear and convincing evidence of some kind of conviction, we do not think it can be said that they are clear and convincing evidence of conviction of a firearms offense. The fact that the front side of the document charges such an offense does not mean Adefemi pled to or was convicted of one. Rather, the summary nature of the court record may well suggest that Adefemi pled guilty to a different, lesser offense that needn’t be carefully memorialized because it gave rise to no enduring, collateral consequences. The reverse side simply fails to offer any clear guidance as to what this offense may have been.
One possibility is that Adefemi admitted to a lesser violation, i.e., an offense graded as less serious than a misdemeanor. Indeed, the court that processed Adefemi’s case routinely affords such treatment in carrying out its primary function: the adjudication of traffic offenses. The Atlanta City Court’s jurisdiction is limited to traffic violations and misdemeanors “arising out of the same occurrence” as a cited traffic offense. Act of Apr. 4, 1996, No. 791, § 3, 1996 Ga. Laws 627, 628; see also Wickham v. State, 273 Ga. 563, 544 S.E.2d 439, 441-42 & nn. 4-5 (2001) (reproducing provisions of Georgia Constitution similarly limiting jurisdiction of Atlanta City Court prior to 1996). In order to exercise this jurisdiction, the court has established a Traffic Violations Bureau (“the traffic bureau”). See Geng v. State, 578 S.E.2d 115, 116 (2003). Once submitted to the jurisdiction of the traffic bureau, an offense “shall be characterized and classified as a traffic violation and shall not be considered as a misdemeanor,” nor entered on the city court’s separate misdemeanor docket. Ga.Code Ann. §§ 40-13-60, 40-13-61. Because the firearms offense with which Adefemi was charged is graded as at least a misdemeanor, see Ga.Code Ann. § 16-11-126, the traffic bureau has no jurisdiction over prosecutions for this offense.
Notably, the document submitted by the INS is consistent with a traffic bureau adjudication by which Adefemi avoided a weapons conviction through a summary disposition fining him $330. Several aspects of the document’s reverse side support this interpretation. First, a line has been drawn through a space for identifying the charge to which a defendant pleads guilty. The failure to complete this section may indicate that the precise offense underlying Adefemi’s fine did not require memorialization because it was a non-misdemeanor traffic violation to which no collateral consequences, apart from those relating to driving privileges, could attach. The form’s silence as to other plea-related information — for example, nothing has been written in a space designated for confirming the voluntariness of any plea— [1278]*1278is likewise suggestive of the relaxed constitutional standards applicable in the enforcement of rules of the road. Cf. Dixon v. Love, 431 U.S. 105, 115, 97 S.Ct. 1723, 52 L.Ed.2d 172 (1977) (finding no due process violation in Illinois regulatory scheme allowing driver’s license to be revoked without prior administrative hearing); Argersinger v. Hamlin, 407 U.S. 25, 38 & n. 10, 92 S.Ct. 2006, 32 L.Ed.2d 530 (1972) (pointing out that adjudications of traffic offenses, even inasmuch as they “technically fall within the category of ‘criminal prosecutions,’ ” are often conducted in manner that prevents Sixth Amendment right to counsel from attaching).
Second, the certification at the bottom of the reverse side of the citation states that “the information on this ticket is a true abstract of the record of this court or bureau in this case” (emphasis added). This boilerplate recitation makes clear that the. documentation is of a form routinely relied upon by the traffic bureau in its adjudication of non-misdemeanor violations.
Third, the location of Adefemi’s signatures on the form are consistent with adjudication by the traffic bureau. As discussed above, the two signatures are seemingly to opposite effect because one is written above the words “On Arraignment, the Defendant Pleads Not Guilty” and the other appears in a section entitled “Appearance, Plea of Guilty and Waiver.” The first signature, however, not only accompanies a “Not Guilty” stamp but also fills a line following the words ‘Waives Trial by Jury.” At the time of Adefemi’s adjudication, such a waiver was consistent with Georgia law providing that traffic offenses “shall be tried before a judge of the court which established the traffic violations bureau.” Ga.Code Ann. § 40-13-60 (emphasis added); Geng, 578 S.E.2d at 116 (reading statute to “restrict[ ] an offender whose case is disposed of in the traffic violations bureau to trial by a judge”).9
For all of these reasons, the form document supports the inference that Adefe-mi’s case was adjudicated as a traffic violation, with the “Probation” stamp meaning simply that Adefemi remained subject to a possible sentence of confinement until such time as he paid the $330 fine imposed. The possibility that “probation” carried this meaning draws force from the document’s silence as to the period of time for which probation was to continue. Regardless of whether the word was used in this sense, it is indisputable that the document fails to specify with any clarity what offense was the basis for any probationary sentence imposed. It is therefore unreasonable to regard it as clear and convincing evidence of a conviction on any specific charge, much less the firearms offense alleged by the INS as a basis for Adefemi’s deportation. Our conclusion is in accord with those of our sister circuits that have considered claims based on the INS’s failure to satisfy its burden of producing clear and convincing evidence of deportability. See Dashto v. INS, 59 F.3d 697, 701 (7th Cir.1995) (holding that clerk of court’s “certified statement of conviction indicating that Dashto had used a handgun to commit armed robbery” was not “satisfactory proof’ of unlawful use of firearm); Murphy v. INS, 54 F.3d 605, 610-12 (9th Cir.1995) (vacating BIA determination based on INS form document and immigration agent’s hearsay statement).
If Adefemi was in fact convicted of a firearms offense, there exist a wide range [1279]*1279of alternative means by which the INS might have established as much. The applicable provision of federal immigration law states that a conviction may be proved by official records of judgments, by docket entries from court records, by minutes.of court proceedings, and by records of penal institutions. 8 U.S.C. § 1229a(c)(3). Alternatively, the document at issue could have been explained by submitting affidavits or testimony from court officials describing the court’s record-keeping practices and explaining the meaning of the form at issue here.
In sum, while the documentation retrieved from the Atlanta City Court does show that a police officer cited Adefemi for a firearms offense, it offers only a cryptic record of how this charge was ultimately disposed. We think the “clear and convincing” evidentiary standard applicable in deportation proceedings requires something more before an individual máy be “compelled by our Government to forsake all the bonds formed here and go to a foreign land where he often has no contemporary identification.” Woodby, 385 U.S. at 285, 87 S.Ct. 483. Accordingly, we conclude that the INS has not carried the burden of proof it bore in establishing deportability on the basis of a firearms conviction under 8 U.S.C. § 1251(a)(2)(C).
CONCLUSION
The Board’s October 4, 2000 decision finding Adefemi deportable under 8 U.S.C. & 1251(a)(2)(C) is REVERSED. Both parties agreed at oral argument that Ade-femi would be eligible to apply for discretionary relief under- section 212(c) had he not been found deportable on this basis. Accordingly, we REMAND to the Board with instructions to permit Adefemi to apply for a waiver of deportation under section 212(c). Our disposition shall not bar Adefemi, should he be denied discretionary relief, from filing a new petition renewing or raising appropriate claims. The stay of deportation entered on March 5, 2001 shall remain in effect until such time as this Court, on motion of the government and after due opportunity by Adefemi to respond, orders it be dissolved.
REVERSED AND REMANDED.
