How to immigrate after a foreign marriage?

If they are unmarried children under 2 1 year old, they can apply for a visa with their mother. Your mother wants to apply for a CR 1 American marriage visa, and you can apply for a CR2 child visa by the way. It will take about 13 and 14 months to get it done. After entering the United States, she will get a temporary green card for two years, and after 2 1 month, she will be converted into a permanent green card for 10 years.

If you are a child over 2 1 year old, you can't apply for a visa with your mother. You can only wait for your mother to get a green card when she arrives in the United States, and then apply for it. It will take about three or four years.

Good luck! ~
