Dependents of H-1B employees (spouses or children) can be in the U.S. in H-4 visa status.
The H-4’s status is contingent upon the continued validity of the H-1B’s status.
H-4 dependents are not allowed to work while in the U.S.
When H-4 dependent children turn 21, they are no longer considered “children” under and they must change to another nonimmigrant status.
If dependents are in the U.S., ISSO can submit the H-4 application together with the H-1B at the time the H-1B is filed.
Extended Family and Domestic Partners
Extended family members (parents, grandparents, siblings, aunts, uncles etc.) and domestic partners are not eligible to come to the U.S. as dependents in H-4 status. They must apply for a B-1/B-2 Visitor visa, or come to the U.S. under the Visa Waiver Program.
