The spouse and children of an H1B visa holder can apply for H4 visas depending on their connection with the H1B holder. H4 visa holders, on the other hand, are not permitted to work in the United States unless they meet certain criteria. These individuals, on the other hand, can attend school and have a legal status while in the United States.
Furthermore, if one‘s H1B partner has become a recipient of an accepted I-140 petition and they are placed in a backlog, H4 spouses can work. If the H4 spouse wishes to apply for permission with the USCIS in this situation, they can file an application.
