How long does it take to immigrate to America by marriage?

You can apply for immigration after marriage.

The application materials need to be very detailed, including the process of meeting and proposing marriage. Mainly face-to-face signing.

It usually takes about 1 year from application to face-to-face interview.

If you pass the interview, you can get a temporary green card after entering the country and apply for a permanent green card one year later. The inspection is very strict, and all your questions are very personal.

During the period from applying for naturalization to obtaining approval, you must maintain continuous residence. You can apply for naturalization three months before you have lived continuously for three years. When you take the oath of naturalization, you must be in the United States.
