I am planning to go for study and I have VISA slot booked for the same. Concurrently my employer has raised H1B petition for me. Incase if I get my F1 VISA and later on I cancel my plan for studies and eye for H1B,will my petition will still be legal or my H1B petition will be cancelled as soon as I get my F1 VISA.
Your H1B petition will NOT get cancelled automatically after you get F1 Visa. Both are independent.
