Listen to what the Indian CPL holders are telling you. You are young; get your college degree first. You will still be 21 or 22 when or if you decide to start with you flight training.
If you get you CFI/CFII - good luck finding a job. You will be hard pressed to work for a US flight school without a green card.
Ton of Indian CPL holders with 250 hours out there unemployed and in debt. Go to school; maybe just get your PPL see if you enjoy it and then pursue aviation after you have gotten a good degree. Remember, if you get furloughed, lose your medical etc. you will need something to fall back on.
And in my humble opinion, I would stay away from flight schools that just cater to foreign students....
