Does the immigration of f4 relatives to the United States affect the immigration of unmarried adult children?

Of course, the minor children of F-4 usually follow their parents, and one parent is the beneficiary.

When the plan expires, the child must be a minor child.

After 2 1 year old, you are not qualified to go with your parents.

You must wait for your parents to get a green card before you can apply for this child, and he must be unmarried.

Green cards are not eligible to apply for adult married children.
