It depends if that person is already legal in the US and if they already have their green card
no no WHAT DO YOU THINK??!?!?!
If they're in the country legally, they should apply for US citizenship.
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.
only if the person marries a US citizen
Yes, they do. Why would an immigrant need to talk to INS about a marriage? Immigrant means they are already residing in the US legally as a immigrant.
nothing she tills has to become a citizen
No rights gained, save for the ability to legalize your residency status if the immigrant entered the country LEGALLY.
Husband.
Yes.
Yes. If the illegal immigrant marries a citizen, they can become a citizen from that.
