I have never been able to think what goes in the mind of the US embassy in Nepal when they issue visa. Do they expect Neplese with 1$=70Rs to pay 10-20k every year and pursue education in US? We all know that even a Neplese from good economic background in Nepal will not be able to do so.If they know the situation of Neplese students or matter of fact anyone from third world country,whats the use of articles like this one? So almost all illegal neplese or undocumented workers are spending their entire earnings back in US. lets try a mathematical approximation.. say we have 10,000 undocumented workers working in OC every year.that to include Neplese,indian,srilankan and so on and so forth.Lets say they make average 6000$ which is $60,000,000 per year .now if 80% of this money in one way or the other goes back to US thats $48,000,000.Again if we account for other undocumented workers in other part of US and multiply that by 10 we come to a significant number of $480,000,000.This contribution is by the students only. So do you think these undocumented workers are doing injustice to US????I am sure it is illegal to do that but is it immoral????
