Permanent Residents are also treated as a "US Person" for the purposes of FAA pilot licensing, up to the largest categories of multi-engine jet transport aircraft.
This doesn't address what recently happened with one specific Permanent Resident that's been in the news, but it's a very chilling effect if suddenly green card status people don't have the right to the 1st amendment.
8 USC 1451(a):
> a) Concealment of material evidence; refusal to testify It shall be the duty of the United States attorneys for the respective districts, upon affidavit showing good cause therefor, to institute proceedings in any district court of the United States in the judicial district in which the naturalized citizen may reside at the time of bringing suit, for the purpose of revoking and setting aside the order admitting such person to citizenship and canceling the certificate of naturalization on the ground that such order and certificate of naturalization were illegally procured or were procured by concealment of a material fact or by willful misrepresentation
According to USCIS, the misrepresentation need not be but-for material. That is, you only need to show that the omission or misrepresentation was relevant to the naturalization inquiry. But you do not need to prove that the government would have denied naturalization had it known the true facts. In that respect, the standard is similar to 18 USC 1001, which has been applied extremely broadly in federal prosecutions. The second Trump administration has much smarter lawyers than the first one, and I'd count on them to be aggressive about using the full scope of section 1451(a).
The wording of 8 USC 1451(a) is not limited to particular questions on visa or green-card applications. The statute refers to how the "order and certificate of naturalization were ... procured" which arguably encompasses everything leading up to the order and certificate. Moreover, the statute has two separate prongs for revocation: (1) the "order and certificate of naturalization were illegally procured"; or (2) "were procured by concealment of a material fact or by willful misrepresentation."
The way government prosecutors interpret these statutes is to push each of these terms and prongs as far as they can logically go. For example, you could argue that the phrase "illegally procured" encompasses any unlawful activity that has some arguable nexus to the visa or naturalization process.
As to the second prong, 8 USC 1427(a) sets forth extensive requirements for who qualifies for naturalization. The requirements are extremely vague and broad:
> No person, except as otherwise provided in this subchapter, shall be naturalized unless such applicant, (1) immediately preceding the date of filing his application for naturalization has resided continuously, after being lawfully admitted for permanent residence, within the United States for at least five years and during the five years immediately preceding the date of filing his application has been physically present therein for periods totaling at least half of that time, and who has resided within the State or within the district of the Service in the United States in which the applicant filed the application for at least three months, (2) has resided continuously within the United States from the date of the application up to the time of admission to citizenship, and (3) during all the periods referred to in this subsection has been and still is a person of good moral character, attached to the principles of the Constitution of the United States, and well disposed to the good order and happiness of the United States.
That third requirement is so broad that almost any fact about a person could be deemed material to the naturalization decision. Now, remember that 8 USC 1451(a) only allows naturalization to be revoked based on concealing or misrepresenting material facts. So it must be the case that you were arguably required to disclose the fact to the government at some point and either didn't or misrepresented the fact. But if you made an omission or misstatement on any government form ever, that could be fair game for bringing revocation proceedings.
8 USC 1451(a) has an express materiality requirement, which I addressed in my comment. The standard of what “would have mattered to an immigration official” can be seen extremely broadly in view of 8 USC 1427(a). In the context of the false statements statute, 18 USC 1001, material facts are those that have the “tendency” to influence the decision maker, but need not actually influence the decision. United States v. Gaudin, 515 U.S. 506, 510 (1995).
The materiality requirement provides some protection. It’s doubtful revocation could be premised on someone having illegally parked their car when going into a USCIS interview. But the standard for materiality is still quite expansive and leaves a lot of room for aggressive prosecutors.
Best to get a citizenship asap
Not because they expect people to say “yes”, but because if they find out later you hide information about your involvement in WW2, they deport you for lying.
No need to prove you were an actual Nazi. You withheld information which is enough grounds for revoking citizenship.
