no
it is illegal
Not without becoming a legal alien. Which usually requires returning to their home country and applying for a marriage visa.
'Illegal alien citizen' is an oxymoron.
A:Yes. The person has committed the crime of bigamy, and his purported marriage in the United States is not a valid marriage.
I am not a lawyer, and as such I am not entitled to give legal counsel, but if the marriage can be proven to be a sham, it can be dissolved and the alien can be deported. This is fairly rare, has happened in few cases, but the other party in such can be held liable for fraud.
The resident would need to wait until becoming a US citizen until filing for residency for the illegal alien spouse.
No. He or she can and will be deported when the authorities notice his or her legal status.
They're still an illegal immigrant. Mariiage alone does not grant US citizenship to an illegal alien. The formal process of citizenship must still be completed.
No. Your second marriage is not legal. In fact, in the United States a married person who knowingly marries again while still married to their first spouse commits bigamy. You need to obtain a legal divorce to dissolve your first marriage.
If you marry an illegal immigrate, he or she will automatically become a citizen of the nation you reside in. This, of course, depends on if you are a birth or naturalized citizen of your respective country. If you are only a resident alien, both of you will have to apply for citizenship status in the country.
Yes, regardless of the alien's status. He can adjust his status and apply for citizenship once he or she marries a U.S. citizen.
No, his mother was a US citizen, he is a US citizen.
