My contract with my client ends next week and my employer recently responded to h1b RFE. Looks like after two weeks I will get approved. However,  I would not have any client(job) after two weeks. and looks like my employer can't find the one.

1. what to do in this case?
2. how can i easily switch to f1 from h1?
3. Any CPT university that will give CPT right away? I already have master's in computer science from USA.

Any relevant suggestion will be highly appreciable.
