On the other hand, do not mistake those in the homeland to be innocent. Many look for desis that are living abroad, hoping they will be their ticket to the States or any other foreign nation of their choosing.

However, the situation that this serial describes is something very rare, and I'm sure it does not happen often. I can assure you that I have personally seen many such marriages that have worked out and are still happily in tact. At the same time, you cannot deny that such things happen and one should always think twice before agreeing to a life-long bond of marriage to a stranger.
