How do I renew my E-2 small-business investor visa?

To renew an E-2 visa, you need to file Form I-129. This falls under the nonimmigrant visa category.
You’ll also need to submit the E supplement and Form I-539. The documents typically required are:

1. Form I-94 arrival/departure record
2. I-797 Notice of Action
3. If you are an employee: your passport and a visa letter from the employer
4. Tax returns from the past two years
5. Payroll tax returns
