Hi Firante, I read your suggestions but my case is different. I already was working on my OPT and it expired on 12/31/2006. Due to some reason I could not apply for H1B on 2006. So inorder to maintain my status I joined a small college and got F1 status on spring 2007. The company which I was working for, rehired me, I applied for H1B and got it approved. So right now I am on F1 status and my H1B starts from 09/10/2007. and I do not want to waste my money by enrolling for Fall 2007 (08/20/2007) because my h1B starts from 09/10/2007. waiting for your suggestion.
