I have  similar questions. Here's the sceneario. I already have a masters and working on second masters which will be done in May 2014. I wont be able to get another OPT since I burned them all. The consultancy says that they will file for H1B  coming April. I think I have to wait till Oct1 2014 before I can work if H1 B is approved. So do I still have to go back to school for Fall 2014 to maintain status. My college or nearby colleges dont participate in CPT.  How soon  can you file for greencard once you are in H1B? How long does it take? Whats the quickest way to get greencard for F1s? I am tired of going to school. I feel like I am at dead end. Any input will be appreciated.
Thanks
