When can Mabel's parents immigrate?

If the parents of an American baby want to immigrate in the name of an American baby, they can only ensure that the parents immigrate to the United States when the baby reaches 2 1 year old. At this time, according to American law, the child has reached adulthood.

If the parents of American babies don't want to wait that long, they can apply for American investment immigration according to their own conditions, such as EB5 or L 1 to EB 1C, depending on which American visa qualifications the parents of American babies meet.
