The H-4 visa is a nonimmigrant visa that allows the spouse and children (under 21 years of age) of an H-1B visa holder to accompany them to the United States. If you are a student seeking to get a green card and your spouse or parent is an H-1B worker, you may be eligible for an H-4 visa.
To apply for an H-4 visa, you must first submit an I-539 form, along with supporting documents such as a valid passport, proof of relationship to the H-1B holder (such as a marriage or birth certificate), and any required fees. If your application is approved, you will receive an H-4 visa stamp in your passport, which will allow you to enter the United States.
Once you are in the United States, you can apply for a work permit, also known as an Employment Authorization Document (EAD), if you want to work while in the country. To apply for an EAD, you must submit an I-765 form, along with supporting documents and the required fee. If your application is approved, you will receive an EAD card, which will allow you to work in the United States.
It's important to note that H-4 visa holders are not eligible to apply for a green card through their spouse or parent's H-1B status. If you are a student seeking to get a green card, you will need to find another way to become a permanent resident, such as through employment or through a family member who is a U.S. citizen or permanent resident.
