Hello there

To become a doctor in an Airforce doesn't matters that in which board/medium you have done your schooling.

Now generally if I would tell that what you have to do is you must have to qualify National eligibility cum entrance test to apply for AFMC and the candidates who qualify National eligibility cum entrance test are able to take admission into that after getting required score.

Now after completing your MBBS degree from a FMC will become an army doctor in Air Force Or in various departments.

To know more about the eligibility and admission procedure and some of the colleges you can refer the link I am attaching below:

I hope it helps you!

Thank you!
