USA Visa & Immigration

The United States offers several visa routes for foreign nationals who want to work, visit, or study. For most work routes, the process starts with a job offer: a US employer sponsors the visa petition before you can apply for the visa itself.

This page introduces the main US visa routes for job seekers in plain language. Choose a category below for the full guide. This information is general guidance from official sources — it is not legal advice, and you should always confirm current requirements on the official websites linked in each guide.
