I don't mean to particularly offend anyone but just state the truth as it is, consider it a reality check.
The sheer amount of filth. Open garbage bins everywhere. There's one just outside the road leading up to the Sahar airport. Extremely bad roads. Try taking a rickshaw from the airport to anywhere through Saki Naka.
The overpopulation.
Schizophrenic, repressed, rude, semi-literate, unhygienic & evil people.
The smell.
Pollution (this can not be emphasized enough).
Unless you plan on coming here to start your own sweatshop, call center or otherwise exploit the cheap labour, it just doesn't make sense. And if you raise kids here they will more than likely grow up to be ignorant douchebags with huge superiority complexes.
I understand that being with parents ranks high among the r2i reasons, but why not sponsor them to come live with you in North America, or move to a somewhat livable city like Ahmedabad or Gurgaon in India?
Many sane people (myself included) have the greatest desire to escape from here, and you want to come back?!
