I dont understand how ranking of Nepal on sending students to USA makes Nepal a rich country Or even Nepali rich citizens. I am sure if we find the complete list, many rich countries are way below in list of sending their students to USA. Just coming to USA does nt make one rich. This is just the indication that Nepalis are so desperate to go out of country because of country's economic condition, unemployment rate, education and so on. those who can gather 8-10 lakhs and have minimum education ( 12 years with fairly good english) tries country like USA, australia, canada, or Uk and those from rural area with not so good educational background tries for gulf countries or korea, malaysia and so on. we nepalis are so poor that we need to send money back home to feed our folks back home.
however, I do agree that getting student visa from nepal is fairly easier than getting visa from countries like inida, china, pakistan and so on based on conversation with folks from these countries.
