U.S. immigration status determines how long you may stay, whether you can work and what rights you have. Immigration law is complex and changes often, so check official sources and get advice from a qualified professional.
Visas
A visa is generally a temporary permission tied to a purpose, such as tourism, study or work. Each category has its own rules on length of stay and employment. Staying beyond the authorized period can cause serious problems.
Green card (lawful permanent residence)
A green card lets a person live and work in the United States permanently, with limits. Permanent residents can travel, but long absences may risk their status. Permanent residents can apply for citizenship after meeting requirements, such as a period of residence. A green card can be lost for certain crimes or abandonment.
Citizenship
- U.S. citizens can vote in federal elections and hold a U.S. passport.
- Citizens cannot be deported.
- Citizenship is obtained by birth, by derivation through parents or by naturalization.
Where to get help
Use the U.S. Citizenship and Immigration Services website for official forms and information. Only licensed attorneys and accredited representatives can give legal advice, so be careful with unlicensed helpers. See our guide to avoiding immigration fraud.
