The first two are from Indian boys living abroad who want to marry girls from India. This of course, is a common phenomenon - taking a 'family-oriented' and 'cultured' bride from India is the norm (as opposed to the wild American memsahibs, I suppose, he he).
But the last two ads are from Indian girls abroad, who are looking for boys from India. I must confess, I was a little surprised.
Take a look.
