Pt 141/61 ???
Pilot Training in the US.
The flightschool that issues you an I-20 is already Pt141 certified.
You have an option to do it under PT141/61. Really no difference with the quality of pilots they produce. As far as the DGCA is concerned, you need to have an "Uncle" over there to get things done.
You can still apply for a J-1 after you complete your CPL. Its all about supply and demand and there is still a shortage of instructors in the US.
Complete your ground studies for the written exams before you come over, it will save you time. I recommend www.gleim.com. You can get a student pilot license by doing your medical with a FAA certified medical examiner in India.
The airline industry has its ups and downs. You will be disappointed if you suffer "shiny jet syndrome" ( mE Fly only with uni-form mentality). If you are willing to ride the tide and work lesser fancy pilot jobs, you will make it in the long run. All the best !!!!!!!!
