So my fiance wanted to take my last name, and also change his first name to be more Americanized. (He already chosen that before we started the K1 process. I told him to hold off until marriage, since it would be a little easier).
Having gone through legal name change myself (using court order) 10 years ago, I think the procedure is, after the marriage,
1. He has to apply for a new Indian passport? Any documentation needed? Will marriage certificate have both new and old name?
2. Update USCIS record somehow? or just do it together with adjustment of status?
3. Can he apply for SSN right after marriage, since technically will he have the right to work being spouse of US citizen? Or he has to wait until the adjustment of status is processed?
(No rude comments please. Just need legally acceptable answers.)
