Sure.

all that you need is math and physics in your 12th and grad.

You have to write CDS exam and you have to clear it, then clear your SSB. Then clear your medics and merits. If qualified everything, then you can join IMA, and if you wrote CDS without math you have to join OTS Chennai.

So graduation from any country doesnt matter as long as you are an Indian Citizen.

I hope I answered you.
