If you married someone who is not a U.S. citizen, you can apply to bring them to the U.S. via a marriage visa. The one you use depends on your immigration status. If you’re a citizen, your spouse is likely eligible for the CR-1 if you’ve been married for less than two years, or the IR-1 if you’ve been married for over two years. This visa usually takes about one year to process. If you’re a permanent resident, you can apply for the F-2A marriage visa, which takes two years or more to process for most people.
