How do f4 over-age children immigrate to America together?

If you are over age, it is impossible to immigrate with your parents at the same time.

Only when your parents have a green card will they start to immigrate to you.

You can't get married in less than ten years.

Otherwise, you will lose your qualification.

In short, if you are over-aged, you will be far away from going to America.

Why not let your parents go to America and find you a citizen to marry?

If all goes well, you can come to America in a year or so.
