Hi Tanveer,
I don't know very much, but I will give you my opinion on a few things.
Having missed a few boats in what can be a very volatile and cyclical industry, I can at least alert you to a few of the very expensive traps that are out there.
1) If you intend training in the states, make sure that the ENTIRE program is planned out, and that you have lined up ALL of the visas and work, BEFORE you part with one single, solitary dollar. Talk and promises are very cheap, particularly in the loosely regulated USA where you will always be at a disadvantage in a dispute. (You are not American and have NO rights under their legal system) Think about the disadvantage an American would have in court in India ! -same for you !
I repeat, DO NOT get your visas one at a time, and check with the consulate that EVERYTHING is in order. (J-1 authorisation "pending" is not worth anything and should be a red flag.)
Realistically, you don't stand a snowball's chance in hell at getting a commuter right seat unless you MARRY a green card. This is because your visas will run out around the same time as you would want to get started at the commuters - and at the moment there are around 6000 Americans, unemployed with ATP's and Type ratings on jets.
2) Use your best advantages to your best advantage. You are clearly an Indian citizen. Non-Indians are not allowed to work in India (except as contractors under special circumstances), so there is much less competition for those first turboprop (or jet) jobs. Court an Indian carrier before you even start training. Start a relationship with them TODAY.
3) Make sure that you get the licences that are most widely recognised. JAR is best, then ICAO, then FAA. Obviously you will need an Indian one, so find out if you can take the written tests around the same time as you take the JAR. That way you will only have to study once.
4) Take your budget and double it ! Just surviving as a flying student can be expensive. If you run out of money before you are ready to fly for the commuters, you will waste a lot of time, and your visas will run out before you finish training. The meter is running ! (at least in the US)
5) Find free money. You might find that there are Canadian options that are cheaper, easier to finance, and that allow you to stick around in Canada where it will always be easier to win a dispute with a school. (especially when OSAP loans etc. are involved.)
6) Get educated and qualified in something else. The most determined and hardworking pilots out there will all tell you that being able to do something else will help you through the rough times. (Trades like electrician are good 'insurance'.
7) Keep you sense of humour. You will need it.
Good luck.
