I am working on my F1 as I am on my CPT program and my CPT gets expired on 25th September. I have used my CPT for than 1 year so I am not liable for OPT but I got my name in the H1 lottery. My question is can I work on CPT after 25th September if not when my company applies for Change of status that is 1st October can I start working after 1st October as it is in the process of Status change request.

There is one more query I am still left with 2 courses that I need to complete if I change to H1 will I be able to continue my degree.

You're not allowed to work after 25th September...

Your company is applying for change of status... what type of visa?
