I believe that anyone can change his/her name (first or last) whenever he/she wishes to do so. You just have to apply for it and follow or requirements.
Sure.
no
Yes, an illegal Mexican can get married in the state of North Carolina. They will need to show a photo ID and a birth certificate.
From what I understand, you can't marry anyone who is already married (unless they divorce their current partner or become a widow)
No you will not become a Mexican citizen but you will have Mexican recidency. Your fiancee can have the option to apply for citizenship later on if she wants.
Lie about ur wife say she is mexican too
It is illegal.
No. Neither will automatically become citizen of the other country.
Not at all. Legal proceedings must be followed to get citizenship.
no, you must file for divorce to be legally divorsed
Yes. It is illegal to marry ANYONE for citizenship purposes only. That person could be deported and barred from life from this country and the citizen that married him/her could face hefty fines or prison time.
yes
Well, because the answer if both of you are of the same country of origin is so obvious, I am going to assume you mean one of US citizenship and one of Mexican citizenship. If you want to get married in the US, the person with US citizenship would have to set up the marriage. I would ask your local government officials.
