H-4 visa

An H-4 visa is a United States visa issued to dependent family members of H-1B, H-1B1, H-2A, H-2B, and H-3 visa holders to allow them to travel to the United States to accompany or reunite with the principal visa holder. A dependent family member is a spouse or unmarried child under the age of 21. If a dependent of an H-1B, H-1B1, H-2A, H-2B, or H-3 worker is already in the United States, they can apply for H-4 immigration status by filing Form I-539 for change of status with United States Citizenship and Immigration Services (USCIS).

Family members may alternatively be admitted in other non-immigrant categories for which they qualify, such as the F-1 category for children or spouses who will be students or the H-1B category for a spouse whose employer has also obtained approval of an H-1B visa petition to employ the spouse. An H-4 visa holder is admitted to the U.S. for the duration of the primary (H-1B, H-1B1, H-2A, H-2B, or H-3) immigration status.

A noncitizen with H-4 immigration status normally is not permitted to engage in employment in the United States but there is one important exception to this rule. All H-4 noncitizens are permitted to study in the United States.
