You can marry anywhere your hearts desire! After you get married the Illegal Resident needs to apply for Permanent residency. You can have the application sent to you just by calling them up (they have computer automated service also).
If they're in the country legally, they should apply for US citizenship.
No.
No, she is not. She will be allowed to remain in the US with her spouse and children, but she will have to apply for citizenship separate from her marriage. The US citizen REMAINS a US citizen. The immigrant remains an immigrant and must follow the legal path to resident immigrant status, and from there to citizenship. Marriage is not a free pass to residency or citizenship.
No it does not make him a citizen, but it you may sponser him for citizenship if you wish.
No. In the US adults regardless of their citizen status cannot be adopted. A legal immigrant can be sponsored by a US citizen for permanent residency and citizenship.
Anyone born in the US, regardless of the citizenship of the parents, can elect to be a US citizen.
you are still a immigrant unless you become a legal citizen on citizenship day.Therefore they have the right to deport you. I am a lawyor and has helped me in similar situations however my expertise comes at a price.
Consult an immigration attorney before the marriage! There are certain forms and procedures that have to be followed in order for the citizenship to be granted. The first step is to get a green card. Citizenship requires a number of years of residency, filing the applications and passing a test. Then one can be sworn in as a citizen.
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.
I believe you are asking if it is legal for an employer to hire a legal immigrant over a American citizen. By "legal immigrant," I assume you mean one who is authorized to work in the United States. Yes. As long as the person hired is legally authorized to work in the United States, his citizenship is irrelevant. Keep in mind that it is illegal in many jurisdictions for an employer to discriminate against a potential employee on the basis of national origin.
no
If the immigrant is a true illegal (i.e. entered the country illegally/without inspection) even a marriage to a US citizen wont prevent him from facing possible deportation. Moreover, an immigrant CANNOT apply for citizenship, they must first apply for legal residency
