Travel India to USA - Valid Visa but passport expires in less than 6 months

[kdeshpan]

Hi All,

This is a question regarding travel from India to USA. Here is my scenario:

My passport expires on Mar 2013 and I am on H1B visa valid up to 2014. Right now I am in India for some family emergency.
I was thinking of extending my stay in India till Sept 2012. But then it leaves less than 6 months for my passport to be valid as it is expiring on Mar 2013
I was thinking of extending my passport once I go back to US from Indian consulate there. Will it be ok to do so?
I heard that there are some restrictions on travel if your passport is expiring within 6 months. Should I get my passport extension while I am in India?
The problem with extending passport in India is that, my proof of residence for last 1 year is in USA. does that pose any problem in getting passport extension in India?

What is the best thing to do in this ? Please advise

thanks
