If you wish to bring family members for the duration of your studies, they will have to enter the US as F-2 or J-2 dependents.
If your spouse will accompany you to the US, you must document an additional US$10,800 per year for living expenses and insurance. An additional US$5,400 is required for each child. US federal law requires the J-2 spouse and children to have adequate health insurance coverage. F-1 students are also expected to obtain comprehensive health insurance for dependents.
If your spouse or child plan to only remain in the US for a short visit, please review the instructions on bringing a family member as a visitor to the US.
