A nonimmigrant visa is tied to a temporary purpose such as visiting, studying, working for a qualifying employer, investing, or participating in an exchange program. The visa category must match the planned activity, and the traveler must remain eligible for admission and status.
Common Temporary Visa Categories
- B-1/B-2 visitors for qualifying temporary business or tourism
- F-1, M-1, and J-1 students and exchange visitors
- H-1B, L-1, O-1, and other work classifications
- E-1 and E-2 treaty trade and investment classifications
- K-1 fiancé visas and limited K-3/K-4 spouse and child processing
The Department of State maintains an official directory of visa categories.
A Visa Is Not the Same as Status
A visa allows a person to travel to a port of entry and request admission. Customs and Border Protection decides whether to admit the person and records the authorized stay. Inside the United States, the I-94 and the terms of the classification control status. A visa can expire while a person remains in valid status, or a person can violate status while the visa remains unexpired.
Intent, Work, and Consistency
Some categories require temporary intent, while others permit dual intent. Unauthorized employment, inconsistent statements, school or employer changes, overstays, and activity outside the category can affect extensions, changes of status, future visas, and permanent residence.
Extension, Change, or Consular Processing
A person may sometimes extend or change status with USCIS, but eligibility and timing vary. Approval of a petition does not always create status, and travel can abandon or complicate a pending request. Review the change-of-status guide before a deadline or trip.
