  4. Flexible timing - Fits co-op programs and gap semesters
  5. Higher conversion rates - Better chance of return offers

  • Career changers - Getting experience while studying

Academic Considerations

Working with Your School

Before accepting an off-season internship:
  1. Check graduation requirements - Will this delay graduation?
  2. Coordinate with advisors - Get co-op credit if available
  3. Financial aid - How does taking time off affect aid?
  4. Housing - Can you sublease? Does company provide housing?
  5. Course sequence - Will you miss prerequisite courses?

Co-op Programs

If your school has a formal co-op program:
  • Register the internship through your co-op office
  • May receive academic credit
  • Some companies prefer official co-op students
  • Schools maintain relationships with companies
Pro tip: Even if your school doesn’t have a formal co-op program, you can often get internship credit through independent study or practicum courses.

International Students

Work Authorization

F-1 Students can work off-season through:
  • CPT (Curricular Practical Training) - Must be part of curriculum
  • OPT (Optional Practical Training) - After graduation or between terms
Important:
  • 🛂 indicates companies that don’t sponsor visas
  • Check with your international student office before applying
  • Some off-season positions are more flexible with start dates for visa processing
