12 and 24 Month Bars

12- and 24-Month Bars on Repeat Participation

The 12-month and 24-month bars are federal regulations that affect eligibility for future participation in the J-1 Professor or J-1 Research Scholar categories. These bars apply to individuals who have previously held J-1 or J-2 status.

These rules are most relevant to individuals who may later pursue a J-1 Professor or Research Scholar program. They do not apply to most J-1 student programs.

24-Month Bar on Repeat Participation

The 24-month bar was established by the U.S. Department of State and applies to individuals who complete a J-1 program in the Professor or Research Scholar category.

An exchange visitor who completes a program in either of these categories is prohibited from beginning another J-1 program in the Professor or Research Scholar category for two years following the program end date.

This restriction also applies to any J-2 dependents.

Example: A J-1 Professor whose program runs from September 1, 2020 through August 31, 2025 would not be eligible to return to the U.S. as a J-1 Professor or Research Scholar until September 1, 2027.

Important: The 24-month bar is not the same as the two-year home residency requirement under section 212(e).

12-Month Bar

In addition to the 24-month bar, J-1 regulations impose a 12-month bar on individuals beginning a new program in the Professor or Research Scholar category if they were present in any J status during the 12 months immediately before the start date of the new DS-2019.

The following exceptions apply to the 12-month bar:

  • J-1 Transfers: The 12-month bar does not apply to individuals transferring between J-1 sponsors under proper J-1 transfer procedures.
  • Less than Six Months in J Status: Individuals whose total physical presence in J status was fewer than six months are exempt.
  • Short-Term Scholar Category: Time spent in the J-1 Short-Term Scholar category does not count toward the 12-month bar.

Important Clarification

If any portion of an exchange visitor’s time in J status occurred during the 12 months immediately preceding the start of a new Professor or Research Scholar program, the entire duration of the prior J program is counted.

If that prior J status lasted six months or more, the 12-month bar applies.

If you have questions about how a prior J-1 or J-2 status may affect future eligibility, you are encouraged to consult with OIP before pursuing a new J-1 program.
