BUILD A CAREER BACK HOME!
These people do not seem interested in helping their homelands.
Wouldn't it be wonderful if they went back home and enriched their rich ethnic cultures with their education, training, and "expertise". After a period of time they would have a nice life for themselves, their kin, and countryman.
But hey, what's important to them is to exploit Americans for suckers, and get the $1000 iPhones, $200 sport shoes, 70 inch TVs, gold chains, and bling.
