Ensure that your employer files the H-1B petition before your F-1 status expires.

Gather documentation of your employment offer and qualifications.

Be prepared to provide evidence of your immigration status.

Consider seeking guidance on maintaining your F-1 status.

Consult with an immigration attorney to determine the requirements.

I’d suggest staying on F-1 status or using OPT while waiting and maybe explore cap-exempt H-1B options if your employer delays too long.
