New and old immigrants in the United States

1. If you return to the United States within the validity period of your visa (you have not been away from the United States for more than 5 months), you can enter the country with your old visa and the new Form 20 without any trouble.

If you return to the United States after your visa expires, you need to apply for a new visa. Because you changed schools, you need a new interview.

3. American visas can only be issued abroad, and there is no place to apply for visas in the United States.
