We live in the Philadelphia PA area. My wife's Philippine Passport expires on Feb 23, 2010. She originally entered the US via a K1 fiancé visa in Nov 2005, and we got married within the 30 day visa limit. Four years later now, she now has a valid US Green Card with all K1 conditions removed.
If we want to visit the Philippines in March 2010, does the Philippine passport need to be renewed ? If so, where ?
Thank You for any help with this.

She needs to obtain a new Philippine Passport. Contact the nearest Philippine consulate/embassy.
