I became a citizen in 2001, after the child citizenship act passed, as my father was naturalized in 1997 (I turned 18 in 2005).
I met all the requirements to be a citizen under the CCA, but never got a passport.
A few years ago, after an extended stay away, I got hassled coming back to the US, and after some confusion, they took my greencard away and made me sign a form abandoning it (but then let me enter the US).
Now I want to apply for a passport, but according to the ds-11 application, I need "proof of legal entry" into the US (green card, or USCIS stamp in an old passport) but which I don't have either.
I'm trying to contact the USCIS for advice, but can't get through on the phone.
I pretty sure I'm a legal citizen, and don't think I can get my green card back. What should I do?
