My first thought is to consider the passport that would be presented to the Philipppine immigration desk.
If a Philippine Passport shouldn't it contain correct visa and maybe CFO sticker?
If foreign passport, then shouldn't the EEC be needed ?
I say this since all 'foreign nations' with 6 months or more stay need an EEC
Even if they are born in Philippines and leaving for the first time.
I may not get much chance to check the current info as we're travelling in Nueva Ecija for a while.
Anyway these are my initial thoughts based solely on what I consider to be logic.
