How long can mainland citizens and American citizens get married and leave?

Tourist status can be passed at any time, but if you want a temporary green card, you can apply for immigration after marriage and need to wait.

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. An application for naturalization can be made three months before three years of continuous residence. When you take the oath of naturalization, you must be in the United States.
