Passport expiring, stamp + h1b petition valid till 2012

[cmn0548]

What is the name of your state (only U.S. law)? TX

Hello all,

I have not traveled to the states yet, but here is my questions:

Please note the points below:

1. I have obtained my H1-b stamp in my passport till October 2012
2. My petition is valid till October 2012
3. My passport expires in July 2010

I have 2 options, either

a) travel to the US on my existing passport and renew INSIDE the US
or
b) Get a new passport in my home country and travel to the US, for the first time, with both passports.

I understand at the Point Of Entry the visa officer MAY stamp my I-94 to the validity of the passport.

I have 2 questions:
* Which option should I go for?
* If my visa stamp is valid till 2012 and I obtain a new passport in 2009, do I have to go for a h1b interview at the consulate again or can I enter the US carrying both passports (my older one will have the valid entry stamp)
