H1 transfer from non profit organisation to profit organisation


I am currently working for a non profit organisation and thay are going to file my H1B in september.

My question is, later on if my H1B is approved and I get a job in a company (profit) can I start working immediately with them or they have to file a fresh application for me and I can start working only in October.

Thank you

The new employer can only file H-1 petition when the cap is opened i.e. April of every year. Once the for-profit H-1 gets approved, you can start working for new employer from that date. You don’t need to wait until Oct to start working.
