I doubt it. Even if we wanted to waste our money there, the chances of getting a F1 visa is slim to none. Maybe there are Indians attending these schools illegally but pretty sure it's not large enough for anyone to notice. Do you have a source?
There is a con where guys looking for a usa visa get accepted at a school with no classes. i wouldnt be surprised if some for-profits did this on the side for extra cash.
Also, some foreigners just dont know any better and get conned.
