Defendants.

INTRODUCTION There are two motions before the Court: (1) Defendant Steel Building’s Motion to Dismiss and (2) Plaintiff’s Motion to Strike the Declaration of Steel Building’s Counsel. For the reasons explained below, the Court will deny the Motion to Dismiss and find the Motion to Strike moot.

BACKGROUND This case stems from an airplane hangar collapse and the deaths of two men—Mario Sontay Tsi and Mariano Coc Och—who Plaintiffs claim were working on the hangar at the time of incident. Second Amended Compl. ¶ 1,

Dkt. 36 at 2. Plaintiffs, as heirs and representatives of heirs of the deceased men, sued several companies, including Defendant Steel Building Systems, LLC, who designed and engineered the hangar. Second Amended Compl. ¶ 2, 5-10, Dkt. 36

at 2-3. Two of the Plaintiffs are Nancy Xol Rax and Ingrid Susana Botzoc Tzi, the widowed wives of Mario and Mariano, respectively. Second Amended Compl. ¶ 18, 26, Dkt. 36 at 4-5. Plaintiffs sued in federal court based on foreign diversity jurisdiction, as

they claimed to be Guatemalan and Salvadoran citizens suing companies based in the United States. Second Amended Compl. ¶ 37, Dkt. 36 at 6; see 28 U.S.C. § 1332(a)(2). Nancy and Ingrid provided affidavits in which they each attested to

being a Guatemalan citizen domiciled in Guatemala. Nancy Affid. ¶ 2, Dkt. 87-1 at 10; Ingrid Affid. ¶ 2, Dkt. 87-1 at 19. They each also claimed they were born in Guatemala and never lived outside of Guatemala. Nancy Affid. ¶ 1, 3, Dkt. 87-1 at 10; Ingrid Affid. ¶ 1, 3, Dkt. 87-1 at 19. And each of them stated they had never entered the United States or applied for or obtained a U.S. visa. Nancy Affid. ¶ 4,

Dkt. 87-1 at 10; Ingrid Affid. ¶ 4, Dkt. 87-1 at 19. Steel Building then filed a motion to dismiss Plaintiffs’ suit under Rule 12(b)(1) for lack of subject matter jurisdiction. Steel Building’s Mot. To Dismiss,

Dkt. 82. Along with the motion, Steel Building filed a declaration from its counsel. Thielbahr Decl., Dkt. 84. In it, counsel stated that one of the other Defendants in this case, Big D, provided employment records for Mario and Mariano to each of the parties. Thielbahr Decl. at ¶ 11, Dkt. 84 at 3; see Thielbahr Decl. Exs. E & F,

Dkts. 84-5, 84-6. According to Steel Building, those documents contained scanned copies of permanent resident cards for both Mario and Mariano. Steel Building’s Memo. for Mot. To Dismiss at 4-5, Dkt. 83 at 4-5.

Steel Building further noted that the permanent resident category listed on Mario’s card was “IR6,” and on Mariano’s the category was “IR1.” Steel Building’s Memo. for Mot. To Dismiss at 7, Dkt. 83 at 7; see Dkt. 84-5 at 7; Dkt. 84-6 at 4. It added that the meaning of these codes is available on the U.S.

Citizenship and Immigration Services’ website, which shows for both “IR1” and “IR6” that the permanent resident was “admitted or adjusted as a spouse of a U.S. citizen married more than 2 years at the time of admission.” Steel Building’s Memo. for Mot. To Dismiss at 7, Dkt. 83 at 7; see USCIS, Chapter 2 – Lawful Permanent Resident Admission for Naturalization, https://www.uscis.gov/policy-

manual/volume-12-part-d-chapter-2. Steel Building argued that the permanent resident cards thus revealed that Nancy and Ingrid were U.S. citizens and so Plaintiffs had not established a factual basis for foreign diversity jurisdiction.1 Steel

Building’s Memo. for Mot. To Dismiss at 7, Dkt. 83 at 7. Plaintiffs responded to Steel Building’s Motion to Dismiss by arguing that neither Nancy nor Ingrid were U.S. citizens. Plaintiffs’ Response to Mot. to Dism. at 3-4, Dkt. 87 at 3-4. In support, Plaintiffs filed numerous documents, including

two reports and a brief professional profile from William Fong, Esq., who Plaintiffs described as “a recognized expert in U.S. Citizenship and Immigration Services . . . security documents.” Plaintiffs’ Response to Mot. to Dism. at 3, Dkt.

87 at 3; Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27-35. According to his profile, Mr. Fong was the managing partner of Fong Ilaga, “a firm specializing in corporate immigration law,” and a professor at Thurgood Marshall School of Law. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 35. Listed

1 Steel Building’s argument is based on the permanent resident cards and their content, not on any of the other employment documents produced by Big D, which presumably are all derivative of the information on the permanent resident cards. Steel Building’s Memo. for Mot. To Dismiss, Dkt. 83 at 7. under his areas of competency in immigration law are “employment-based & family-based permanent residence.” Plaintiffs’ Response to Mot. to Dism. Ex. E,

Dkt. 87-1 at 35. In his reports, Mr. Fong explained that he reviewed the scanned copies of both Mario’s and Mariano’s permanent resident cards and noticed several

“anomalies” on each card that were “inconsistent” with what he would expect to observe on validly issued permanent resident cards. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27, 31. Addressing Mario’s card first, Mr. Fong listed four irregularities. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27-28.

First, he pointed out that the name on the card, “Mario Rigoberto Sontay Tzi” did not match the name contained in the wavy line above the picture on the front of the card. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27. Mr. Fong

observed that the name in that wavy line appeared to be “Martinez Lopez Daniel.” Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27. Second, Mr. Fong noted that the picture on the front of the card was “not a standard USCIS digitized photograph.” Plaintiffs’ Response to Mot. to Dism.

Ex. E, Dkt. 87-1 at 27. He stated that USCIS requires that such a photograph be “centered” with the individual “facing forward” and their “full face visible,” including their ears. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 27. He observed that the photograph on Mario’s card did not show both of the individual’s ears and did not appear to be a full-frontal image. Plaintiffs’ Response

to Mot. to Dism. Ex. E, Dkt. 87-1 at 27. Third, Mr. Fong noted that the typeface of the headings on the front of the card was inconsistent with each other. Plaintiffs’ Response to Mot. to Dism. Ex. E,

Dkt. 87-1 at 28. He explained that the heading “Category” was in bold unlike the other headings. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 28. Fourth, Mr. Fong identified two anomalies on the back of the card. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 28. First, he noted the line indicating

the revision date for the edition of the card was in bold typeface, whereas the notation “Form I-551” was not bolded. Plaintiffs’ Response to Mot. to Dism. Ex. E, Dkt. 87-1 at 28. Second, he observed that the revision date listed was “02-2016,”
