hey makar tantra could you please explain me what do you mean by "after all course works are completed". Actually i applied for my OPT in Feb when i was in last semester of my study. I completed that sem and received my OPT card too. Now university is saying me that i need to do one more 3 credit course in order to get my masters degree. this is my situation. and i cant leave my work as they are hiring me in permanent position in late september. So i wanted to know since i am again taking a class, do i need to re issue my i-20? or i can just enroll in class and am i allowed to work or not after enrolling in that class?
