Hey, recently while returning the usa after completion of my vacations, the immigration officer wrote CWOP on my visa and sent me back home, believing I am not a student. Because I was living in Chicago and my university is in Wisconsin, can anybody help me on that.

"CWOP" is "cancelled without prejudice", meaning the cancellation should not automatically keep you from getting another visa. It is not credible that you live in Chicago and attend school in Wisconsin. Did you have your school registration for the Fall semester, tuition payments, and were entering before the semester started?

Yeah u right, staying in Chicago was a big mistake, Its not easy to get a visa now, but I will try to convince the consulate officer. Let see!

Are they any chances for getting a new visa now

Yes, but you will need a lot of evidence to show you are a bona fide student.

What do I need as evidence to be a bona fide student apart from transcript, student id, tution fees. Look forward for hearing from you.
