Green Card vs. Visa: What's the Difference?

The short answer

A visa is permission to enter or stay in the US temporarily for a specific purpose. A green card makes you a lawful permanent resident — with the right to live and work in the US indefinitely, and eventually apply for citizenship.

Visas are a door, not a destination

Think of a visa as a door that lets you into the country for a defined reason and period — work, study, or a visit. It generally expires, and staying past that point without renewing or changing status creates real legal risk.

Green cards are a status, not an event

A green card isn't temporary. Once approved, you can live and work in the US permanently, travel more freely, and after a set number of years, apply to become a US citizen through naturalization.

Can a visa lead to a green card?

Often, yes. Many green card holders started on a temporary visa — a work visa that led to employer sponsorship, or a student visa that led to marriage-based sponsorship, for example. But not every visa allows this path, and the transition has its own rules and timing.

Which one do you need?

If your goal is temporary — a job assignment, a degree, a visit — you likely need a visa. If your goal is to live in the US permanently, you're likely looking at a green card, possibly starting with a visa along the way.
