Yeah! I know it is just so easy to blame the indian immigration.
I have 2 kids. I will never take the RISK of doing something that stupid. I know Viraj and Vishali thought - ha! what the heck lets give it a shot! If we get an entry well we saved $200 on Visa cost. Now it costed you the ticket money for 4 people. That perfectly fits the proverb - Penny wise and Pound Foolish.
You have PIO and a old Visa for your kids - give me a break man!!! It is your irresponsibility and inertness that costed your kids hassle and dont blame the indian government for that.
It is so perfect to hide behind racism while being incapable and irresponsible. Now you know what to do when you go to india next time, right?
