What about legal alien kids who come (sent by parents) here legally for undergrad studies...pay upto 100K in tuition fees, and be sent back if can't get job visa or other legal immigration problems? Wouldn't you argue, this kid knows nothing , he was shown the american dream, he deserves greencard/citizenship?

This is just further evidence that the system is terribly broken. And, of course, in this case the kid getting sent home still has the illegal immigration option. He/she's no worse off than someone like Vargas, though residing illegally is probably more difficult when you're already on file with the gov't.

There is law for a reason

So you say. Clearly it's not working out very well, or situations like this (and many others) wouldn't pop up so often, and immigration reform wouldn't be a hot-button issue of national importance.

... and 300 millions American citizens and legal aliens abide by it. Do you want make all of them feel idiots?

They can feel however they want to feel; I don't particularly care. They do have one huge benefit over Vargas' situation: they don't live in fear every day that someone will find out about them and they'll get sent back to their birth country.
