What is Visa?
An official document or stamp placed in a passport that allows a foreign national to apply for entry to the United States for a specific purpose and duration.
Understanding Visa
Visas are categorized as immigrant (leading to permanent residence) or nonimmigrant (temporary). Common nonimmigrant visas include tourist (B-1/B-2), student (F-1), and work visas (H-1B, L-1). Visa approval doesn't guarantee entry - CBP makes the final admission decision.
Examples
- 1H-1B work visa for specialty occupation
- 2F-1 student visa for university study
- 3K-1 fiancé visa for marriage to U.S. citizen
