I am a PhD student on F1 visa (applies work authorization restrictions). I am paid as RA in our department (20 hours/week). I have an internship offer for summer which extends through first few weeks of fall semester. Now my question is whether it is allowed to switch from (paid) full-time internship to RAship, given that I will be an intern (off-campus) for first few weeks of fall and back to school for the rest of the semester? Or do you suggest I change my full-time internship to part-time for fall semester?
