Urgent! My boyfriend immigrated to new york with his family and now has a temporary green card. Can I stay in America when I travel and marry him?

Let's not discuss whether to get married legally, which means there is no age for marriage in the United States.

The problem now is that even if you get married, you can't get a green card. This is because your boyfriend is a green card, not a citizen. Only when you get a green card and become a citizen can you get a temporary green card (you can apply for it after five years). If you marry a green card holder, you will get nothing.

So you can only wait five years, or you can travel to the United States first, then find a language school and change to F 1 status until your boyfriend becomes a citizen.
