Used for citizenship?

There are only two things that revoke citizenship:

1) if it is proved you lied on your citizenship application

2) if you commit treason (advocate armed overthrow of the government). This applies to *all* citizens, not just naturalized ones.

Therefore, the only recourse you have is to marry someone else filthy rich so you can gloat and brag to the former wife/tramp.

Once she is a citizen you can't do anything about it. If you had found out while she still had her 2 year green card you could have reported her and filed for divorce and she would have had to leave the country

The fact you have kids together means you were not just used for citizenship. Most people who use another person for citizenship don't have kids with them which would tie them to that person until the kids are at least 18 years old.

She can't have used you for citizenship only, as she could have become a citizen even when being divorced from you.

No, her citizenship won't be revoked and U.S. citizens can't be deported either.

No ... you must have been with her 3 years to get her citizenship

Time to just move on

No once she has her citizenship there is nothing you can do
