J-1 Bars

12- and 24-Month Bars​

On Repeat J Program Participation

The purpose of the J-1 Exchange Visitor Program is to facilitate understanding between the U.S. and other countries through mutual exchange. To encourage this goal, the U.S. Department of State created bars on repeat J program participation. The 12- and 24-month bars may apply to you if you previously spent time in the U.S. in J-1 or J-2 status and now wish to return as a J-1 Research Scholar/Professor. Depending on the duration and category of your previous J program (see box 4 on Form DS-2019), you may be subject to a 12-month bar, a 24-month bar, or neither.

Note:

  • These bars do not prevent you from returning to the U.S. in a different immigration status.
  • ​These bars are different than the two-year home residence requirement (212e). There is no waiver for the 12- or 24-month bar.

The charts below show how long you must wait before you can start a new J-1 Research Scholar/Professor program based on the duration and category of your previous J program. The wait time begins the day after your previous J program ended.
