Passport Questions/Do I need to carry both?

[immihelp]

I got my minor passport (vaild for 5 years, expiring in August,2011)
reissued with new passport number, which is valid for 10 years. My F-1, US visa is stamped on my minor passport mentioning that passport number.

Is any action required on my part regarding F-1 visa or just carrying both
the old and new passport during travel is enough.

Just carry both passports.
