An H-4 visa is a dependent visa that allows the spouse and unmarried children under the age of 21 of an H-1B visa holder to live and study in the United States. To apply for an H-4 visa, the applicant must first have a valid H-1B visa holder as a spouse or parent.
There are several benefits to obtaining an H-4 visa. H-4 visa holders are allowed to live and study in the United States for the duration of the H-1B visa holder’s stay. They are also eligible to work in the United States if they obtain an employment authorization document (EAD). Additionally, H-4 visa holders can travel freely in and out of the United States.
