An H4 visa is issued to dependent family members, such as spouses or children under 21 years of age, of H1B visa holders. This allows dependent family members to accompany the H1B visa holder to the United States during their stay. Additionally, if the H4 visa holder would like to work in the United States as well, they have the option to obtain an EAD which allows you to work with an H4 visa.
