I am an international Ph.D. student with F1 status. I'm wondering is it possible to simultaneously work as Research Assistant (20 hours/week, on-campus) and also work on part-time CPT (2 hours/week, off-campus), i.e., in total, 22 hours per week, during the academic year (Fall, Winter, and Spring terms)? I will take courses for the part-time CPT work.
I have asked this question from the international office of our university and they answered there is no problem with this. I have also found this website which indicates it is possible.
