I know to some extent the US watches everyone, but what I am thinking of is whether newly naturalized citizens are watched to see if their naturalization process seems insincere in hindsight. For example:
- If a newly naturalized citizen immediately emigrates from the US back to their country of origin (although continues to file and pay relevant expat taxes).
- If a newly naturalized citizen, who became a citizen after 3 years of residency because they're married to a citizen (rather than the usual 5 years, src) immediately gets divorced. (Obviously you have to present evidence of a bona fide marriage - which mine is - to even get citizenship, this is hypothetical)
- If a newly naturalized citizen, who took an amended oath NOT swearing to serve in the US military, due to 'deeply held religious or moral code' (src), then joins the military, gets a concealed carry permit, gets an FFL or similarly seems to not be very pacifisty.
- If a newly naturalized citizen immediately joins the Communist Party, which although not illegal (src) would have disqualified them from citizenship if they'd joined the CP before applying.
I know there are certain things where the US can revoke citizenship, like serving in a foreign military who's at war with the US, but none of my list are illegal activities in themselves.
Does the US watch for and/or revoke the citizenship of new citizens for this kind of stuff?
(1) could happen if my parents get sick or injured and I need to become their carer, for example. Also, I do intend to modify my citizenship oath/affirmation (3): I have religious conviction against bearing arms for any worldly nation, but I am willing to use force in private-individual self-defense, and I feel like the nuanced distinction between those may be lost on any watchdogs.
I would also be curious whether misdemeanors or felonies shortly after citizenship can result in revocation.
