The US Department of State advises that university policies governing J-1 off campus employment take precedence over federal regulations regarding J-1 student off-campus employment. UCSB Graduate Division policy states:
All appointments or combined appointments are limited to 50% time (an average of 20 hours a week) during the academic terms. The 50% time restriction will apply without exception for international students, dependent upon their visa type or country of origin (consult the Office of International Students and Scholars for further information). All continuing students may work 100% time during the summer, provided they were registered and paid fees for the immediately preceding spring quarter.
If you encounter any financial hardship during your time at UC Santa Barbara, please consult an OISS advisor so that we may provide you with support and resources.
