U.S. Visas: Immigrant vs. Nonimmigrant
U.S. visas fall into two broad groups: nonimmigrant visas for temporary stays (tourism, study, or temporary work) and immigrant visas for people coming to live permanently — which lead to a green card. The right category depends on your purpose and how long you intend to stay.

Immigration is federal law and policy changes frequently. This is general information, not legal advice — verify current rules at travel.state.gov and uscis.gov and consult a qualified immigration attorney.
A U.S. visa is permission to seek entry to the United States for a particular purpose. They split into two broad groups.
Nonimmigrant visas — temporary
For a temporary purpose and stay, such as:
- Visiting (tourism or business) — B-1/B-2;
- Studying — F (academic students);
- Temporary work — categories like H, L, and O, each with its own employer and eligibility rules.
When the authorized stay ends, the person is generally expected to leave (unless they change or extend status).
Immigrant visas — permanent
For people coming to live in the U.S. permanently. An immigrant visa is the path to a green card (lawful permanent residence) for someone processing from abroad; those already in the U.S. may instead use adjustment of status.
Which one applies?
It comes down to purpose and duration — a temporary stay points to a nonimmigrant visa; an intent to live here permanently points to the immigrant path. Categories, caps, and requirements change often, so confirm details on the Department of State and USCIS. For help choosing a path, connect with a lawyer. See also the immigration system overview.

- What's the difference between an immigrant and nonimmigrant visa?
- A nonimmigrant visa is for a temporary purpose and stay — like tourism, study, or temporary work. An immigrant visa is for someone coming to live in the U.S. permanently, and it leads to lawful permanent residence (a green card).
- What are common nonimmigrant visa types?
- Common categories include visitor visas (B-1/B-2), student visas (F), and various temporary work visas (such as H, L, and O classifications). Each has its own rules — check the Department of State and USCIS for the current requirements.
- Does a nonimmigrant visa let me stay permanently?
- No. Nonimmigrant visas are for temporary stays. To live permanently you generally need an immigrant visa or to adjust to permanent resident status — see how to get a green card.
- Where do I check current visa rules?
- The U.S. Department of State (travel.state.gov) handles visas issued abroad, and USCIS (uscis.gov) handles many petitions and status changes. Requirements and categories change, so rely on those official sources.
