Passport Validity and Expired Passports
Passport Validity

All visa applicants should have a passport valid for at least 6 months past the date of their anticipated departure from the Philippines. Visas will not be issued to applicants with passports that will expire in less than 6 months.

A Valid Visa On An Expired Passport

A visa is valid until the date it expires, even if the visa is in an expired passport. To use a visa on an expired passport, bring the expired passport containing the valid visa and the 'new' valid passport. It is not possible to "transfer" a currently valid visa into a new passport.
