How long can you stay in the US with the J1/J2 Visa?

The length of time you will stay in the U.S. under your J-1 visa depends on your particular program, but, except under some cases, the limit can be seven years. As for the holders of the J2 visa, the length of the visa varies, since the holders of the J2 visa are permitted to remain for the same length as the holders of the J1 exchange visa. So, if their program is going to last two years, then the holder of the J2 can stay for the full term of two years or less.
