Frequently asked questions
Answers to the most common doubts about immigration paperwork.
What is a non-immigrant visa?
A non-immigrant visa allows temporary entry to the US for a specific purpose: work, study, tourism or exchange. It does not grant permanent residency.
Unlike immigrant visas, they must be renewed and have strict conditions on what the holder can do while in the country.
