How long can I stay in the United States on a visa?

The duration of stay in the United States on a visa depends on the specific visa type you hold. Some visas allow for longer stays, while others have shorter durations. For example, the B1/B2 visitor visa typically permits stays of up to six months, whereas student visas (F or M) are valid for the duration of the educational program. Non-immigrant work visas such as H-1B may grant authorized stay for up to three years initially, with potential extensions. Immigrant visas, like family-sponsored or employment-based visas, allow permanent residency in the United States. To determine the specific duration of your stay, consult the visa type guidelines on the US Department of State website or contact your local US Embassy or Consulate.
