Passport validity at time of visa application

[freddie]

my parents intend to visit me in US in august 2010 until november 2010, however one of their passports expires in feb 2011. They will go for visa interview for b2 visa in july 2010.

Do they have to apply for a new passport or will they be able to manage without renewing?

thanks in advance.
