First of all congratulations if you have made it so far !! Well, as an international student in USA, you must be holding F1 visa. Under the F1 visa , students are only allowed to work part time ( 20 hrs a week ) on campus job with the permission from university. Under no circumstances you can be a full time internationals student and work more that 20 hr/week. Once you complete your course, you will then have to apply for Optical Practical Training ( OPT) through your school.
