I am not sure how meera come up with ratio of 9:1.  well, girls might have even higher numbers of guys to choose from if they wish to go back home, dont you think so?  while i believe ratio is not 1:1, i seriously doubt the ratio is that big.  regarding educate, drive and job hunt issue, i guess driving takes less than a week, and everyone has to go through same job hunting process.  if someone has bachelors degree from Nepal and has capacity to pursue masters here, it wont take much time to catch up with others here.  well, doing undergrad here does not guaranteed jobs.
