1.I am in India and my I-20 has been terminated. What should I do to reenter in the United States? 2.Can I reenter the United States with an I-20 issued by a private university for a full time course and not by public university?
1. You will have to look for another school/visa.
2. As long as the school is authorized to issue I-20, you can apply for an F-1 visa. But make sure the school is not running into problems like Tri-Valley University did.
