The U.S. Department of State has certain restrictions on J-1 researchers and professors who make repeat visits to the U.S. to begin new programs. This does not apply to those who travel, extend, or transfer their DS-2019 during one consecutive period of time. However, if a J-1 researcher or professor completes an exchange visit and wishes to return to the U.S. for another exchange visit, restrictions may apply in the following situations:
Please contact an advisor at Berkeley International Office for information about planning future visits to the U.S. in J-1 status, especially if it is likely that the return visit will be within twelve months of completing your current visit.
