Roadtrip,
Let me see if I can inform a Boeing 747-200

Captain why we have so many foreign student in US. The first questin you should ask yourself is why the US government Issue them student visas to come here to US???
First of all countries such as India, China, Malysia, etc.. have not the resources that US have for flight training such as airplanes, instructors and other things you need to get your license. The cost of flight training is MUCH cheaper and MUCH MUCH easyer compared to other counties. You can pretty much get your commercial+IR+ME in 9-10 months in US with a cost about 30 to 40ks, maybe even chaeper. Once they are done these students go home and convert their license and get picked up by airlines flying Airbus 320, ATR, or Boeing 737.
So, have you figured out why your government issue them a student visa?? If not, let me tell you it is all about money. These students come to US and spend 30 to 40k to US flight schools, they also pay US government significant amount of money for their visa process, and once they are here in US they have to pay TSA (transpotation Security Administration) 130 US dollar before starting their training. So you do the math how much money your government is making to send these guys over here. And don't forgett the schools have to pay TAX too

.
AND MOST OF THEM USUALLY GO BACK HOME TO FLY AIRBUS OR BOEING,,NO NO THEY DON'T WANT TO STAY HERE. A shiny airbus is waiting for them.
I hope this info change your thoughts about us international students that seeks training in USA.
Good Luck
