US visa

Recently went to attend the US visa interview in Chennai consulate. Horrible experience this time..
1)Do not go to Consulate 15 minutes before the interview time. It really does not matter where you are standing in the queue, 15 minutes before the interview you will be called to come closer to the security check.
2)Only case when there is no people waiting they may allow you to go inside embassy in advance. But that is like lesser crowd in Tirupathi temple.
3)Elders do no take a noon interview. You just need to enjoy the Chennai climate standing in the mount road if you reach in advance.
It was interesting to know chennai embassy processes largest number of Visas. It is not going to reduce anytime soon. My approximate estimation of the number attendees =
(2*30% of people who went to US on a job) + (1*80% of guys who got married ~a year ago at the same time and working in US) + 10% of the experienced guys who joined in a new s/w company without a visa + 50% of freshers who joined s/w company
That is the minimum, there is hell lot of other industries who also work with Americans. So it is never going to come down.
One more interesting piece I found after my weekend outing with my collegue who is from IIT delhi is there apprx 5 times more people from IIT chennai go to US than IIT delhi. Somebody is listening?
