Please do not erase my correct answer. That message board is a wonderful place to go to for help in the process of an illegal immigrant becoming an legal resident because I have helped my husband do so.
It is legal in the United States for an illegal immigrant to marry a US citizen. Once the marriage is legal, the illegal immigrant becomes a legal immigrant and can stay in the US for the course of the marriage.
No he cannot
the US citizen shouldn't
If you are married, you can apply for divorce.
no not unless they where married to a USA partner.
Anyone born in the US, regardless of the citizenship of the parents, can elect to be a US citizen.
=An immigrant is NOT an alien.==The immigrant would still be legal because they were married to a US citizen.=
no
Yes. If the illegal immigrant marries a citizen, they can become a citizen from that.
No.
If an undocumented (illegal) immigrant is married to a U.S. citizen, then they are a U.S. citizen. So their divorce from another U.S. citizen won't affect the status of their child at all.
My guess is no. You have to prove that you have a real marriage to stay.
