Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a non-immigrant visa for a temporary stay, or an immigrant visa for permanent residence. Visitor visas are non-immigrant visas for persons who want to enter the United States temporarily.
Here are the two types of visas for tourism, business or for a combination of both purposes:
- Business visa category B-1
- Tourism visa category B-2
- Combination B-1/B-2
