May I need to renew my passport which is valid till 23 Nov.2008?I'll be traveling on business visa.?

I don't want to take risk to renew my present passport as it may take long time. My present passport was issued from Gujarat and now I'm working at Bangalore...so it may take long time to finish formalities. My trip is fixed up in July 2008 to Sept.2008. What documents are required to submit if I wish to renew my passport at USA before Nov.2008?

Indian passports are excempt from the 6 month rule.

You are fine to make your trip to the United States until September even though your passport is only valid until November.
