Marriage to a US citizen does not automatically provide citizenship. There are other aspects that still have to be met. It would be well worth the cost to make sure it is done correctly.
If they have a green card, they can work.
No he cannot
If you are married, you can apply for divorce.
the US citizen shouldn't
My guess is no. You have to prove that you have a real marriage to stay.
No. Green cards are not issued due to getting married.
An American citizen can marry an immigrant who already has a green card in the United States. The immigrant is placed in preference category 2A, and is placed on a waiting list.
Right after the marriage , the thai immigrant should apply immediately for a green card , he/she has the right to do so, and then after obtaining green card she/he can stay in US whatever he want , even after getting a divorce. Your question is ambiguous, be more specifically . What's your status ? Have you applied for a green card yet? If you get divorce, before you got some legal documents you can be deported. Call a lawyer, he can help you.
she's not a u.s. citizen yet but she's a legal immigrant and legal immigrants can work. then(if you're a u.s. citizen) after three years being married to you she can become a u.s. citizen. If she was here illegally when you married her and have not filed any paperwork to adjust her status the she is subject to deportation whether she is married to you or not. If you think the green card application is expensive just wait to you see the bills you face if she gets caught and you need to hire a lawyer to keep from getting her deported.
No it will not be easier to get a green card. And how did they illegally marry? If they were issued a marriage license, and they did not lie on the application, they are legally married.
An American citizen has the right to petition for green card for relatives. Once they are married and have their papers ready the US citizen can petition for spouse's green card. Subsequently the kid can also become US citizen or green card depending on the support papers which can be shown for either of them. During the stay in US its very important for immigrant to have papers for a legal and authorized stay in US.
If one is an immigrant to the United States of America and is in need of a green card so that they may work legally, they need a green card lawyer. Green Card lawyers are found in green card law agencies.
