What should I do if my visa to the United States expires?

1. If you have a study visa, you must enter the country according to the entry time on the I20 form. If you pass that entry time, you must replace the I20.

2. If it is a tourist or business visa, the visa is valid for one year, and the stay in the United States is usually half a year. Therefore, there is no saying that it will expire without leaving the country. You can leave the country at any time within this year.
