If you're granted an employment-based visa such as H-1B, L-1, O-1, or EB green card categories, your spouse and unmarried children under 21 can typically join you in the U.S. under dependent visa categories.

They may be allowed to live, study, and sometimes work in the U.S., depending on the visa category.

Each family member must apply separately for a dependent visa, but their application is typically tied to yours.
