there is no actual survey taken so far on what percent of Nepalis do desk job vs. what percent do menal jobs in USA.  so if we are randomly throwing numbers out there then i would like to say at least 25% of the Nepali population have professional jobs given the fact that everyday around 30-50 students apply for student visa and most students actually do graduate and are able to find jobs eventually. but again, if their life  style was so  better in Nepal or is goign to be better in Nepal if they returned,  then the door is open, they can return. who's stopping those ppl? Nepali mentality is to complain about everything in their life. they would complain if they were in Nepal and they are complaing here now that they are in the USA. USA is still the most powerful, biggest economy , the most diversed and easy to immgrate country in the world. if they can't make it here and they think their life would be better in Nepal or else where then no body is putting gun in their head to stay here. you're slave of your own high  ambitions, don't blame the USA. 

now i can understand, if they are  used to of working like 6 hrs in govt office back in Nepal and were used to of making extra income by bribes, then the hard work isn't their cup of tea and obviously such practices have made them incompetent over the years to compete in real world where bribes and slacking off at work won't cut in. 

 and as far as working in gasstations and cabbies go, they ware still making lot better than what they would be making in Nepal or katar or dubai.if they are legal they would save the expenses of educating their children and the list goes on with other opportunites.
