The whole CFO thing is a complete farce in my opinion. Nobody in Philippines bothers to tell you anything about it so I'd guess theres a lot of people that get turned around AFTER theyve paid their terminal fees at the airport!
I only found out about it here and it was a complete surprise to my fiancee. Their website is one of the worst Ive ever seen and gives you conflicting information.
They dont even tell you the full requirements before you go there!
Make sure your wife has pictures of you together. They will ask, and they won't give you the sticker if she can't show them one!!
