F4 immigrants in the United States.

F4 is a compatriot immigrant. Who are the brothers and sisters of American citizens who are the main applicants, and the rest of the family members who are applied are incidental applicants. If the main applicant can't go, everyone can't expect to go.

If the mother has a record of overstaying, the consulate will have a background check. But no one dares to say whether there is a chance to get the right to enter the country. Since there is this obstacle, what is the argument that overstaying is decent and necessary? Write a letter in English to prevent the interviewer from making trouble on the spot. If the interviewer wants to stop you, he will definitely bring this up and then take out a letter of explanation to see if he can convince others.

You are not the principal applicant. If the main applicant stays, you will never go out. Why not let everyone go out together? Once you get a green card (as long as the visa is approved, your immigrants will get a green card soon, at most a few months), let the old man come back. With a green card, you can continue to work in the United States until you get citizenship.

If you are over 2 1 year old now, you will be in trouble, but the Law on the Protection of Over-age Children was promulgated in 2000, depending on the age at which your family applied for F4.

The point is that your mother overstayed. If it takes a long time, it's easy to say. If it can't be signed two or three times at a time, it will be delayed enough. If it is new, be prepared.

-Your father is the main beneficiary. It doesn't matter. The family went to the interview together. If the interview is temporarily unsuccessful because of your mother, people will say so. At this time, let your mother apply to give up. Step by step, and the rest is as above.
