On May 19, 2005, DOS published a final rule on participation as a J professor or research scholar. The rule:
- Extended the maximum period of program participation in the professor and research scholar categories from 3 years to 5 years but eliminated extensions of stay beyond 5 years in those categories except for G-7 programs
- Created a 2-year bar on "repeat participation" in the professor or research scholar categories, for professors or research scholars who have already completed a program as a professor or research scholar.
This rule became effective November 18, 2006.
Note: The final rule as published on May 19, 2005 erroneously applied the "12-month bar" to prior F students and their dependents as well as prior J exchange visitors and their dependents. DOS removed the erroneous reference to F nonimmigrants in a correction notice published at 70 FR 36344 (June 23, 2005).
