My boyfriend immigrated to the United States with a green card, but I have to wait for him to come back and marry me. How long does it take to immigrate to America after marriage?

If your boyfriend has got a green card, he can apply to take his family to the United States when he goes back to marry you, and you can go. It takes about 1 year, and the longest is five years ~ ~

Before you get a visa, you must pass a medical examination. If you find that you are pregnant during the physical examination, you won't get a visa. Because if you give birth to a child in the United States while pregnant, the child will be an American, so be sure to check whether you are pregnant.

If you are pregnant, you should do it with your child from the beginning ~

Good luck ~ ~
