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.
no
Yes. If the illegal immigrant marries a citizen, they can become a citizen from that.
Not without becoming a legal alien. Which usually requires returning to their home country and applying for a marriage visa.
yes you do!
No. citizenship has to do with where you were born, and where your parents were born. It has nothing to do with marriage.
only if the person marries a US citizen
Marriage is a wonderful event. Yes, if a female US citizen legally marries a non US citizen in the state of Michigan, they are indeed legally married.
A:Yes. The person has committed the crime of bigamy, and his purported marriage in the United States is not a valid marriage.
Yup
This has nothing to do with your marriage license. This is about your marriage certificate. Effective October 6, 2014, your Vermont marriage certificate is legally valid in Colorado.
The marriage may be valid, but once the person is deported, for any reason, he/she is guilty of "agrivated re-entry" if he/she ever returns to the U.S. The spouse is welcome to live with the illegal immigrant in his nation of birth as husband and wife.
The illegal foreign national will still be required to follow the prescribed USCIS procedures. This could mean the person will be required to leave the U.S. and then apply for a visa for reentrance. A foreign national whether illegal or not is not automatically granted permanent residency or citizenship status by marriage to a U.S. citizen. Marriage will sometimes (but not always) change the priority status given to an applicant's request. United States Citizenship and Immigration Services, http://www.uscis.gov
