Like I have replied above, bringing the son to India not necessarily is a problem. There are great schools here. When parents are ready to send kids to other countries w/o any problem.. why the reverse logic does not work. I studied in India and work in US, my education is solely in India... I don't see a problem there.
Probably a little common sense will tell you whether they are lying or not. They seem to know all the right steps to run a motel business, they also didn't visit Indian for 16 years? When did the realisation happen to them that the lawyer goofed up? They knew it from day one and hence they did not visit India (they would not have been allowed back to US if they did). Let's say they came to know after a year or 2 when most usually people would try to visit India. In which case, they could have withdrawn the application. Once you know they started this stuff with a lie, then everything around them has no basis. You don't need to know them personally to know they are cheats.
