The spouse or child(ren) of an F-1 visa holder may accompany the F-1 student to the U.S. under certain provisions. Each dependent must have his/her own I-20 and apply for his/her own F-2 visa. Additional financial support must be shown for each dependent for each year of the student’s study. Documentation of an additional $4000 for a spouse, and $2000 for each child must be demonstrated in order to receive the I-20 for each dependent.
If the dependents are not traveling with the F-1 visa holder right away, they can receive their I-20s at a later date.
There are special rules for F-2 visa holders.
