Very good post. We had a bit of hassle with this as my wife did the CFO seminar but they wouldn't issue a sticker because she was married to a British National yet moving to a Middle Eastern country, which didn't fit into their rules (computer says "no"...). This didn't cause any problems at the airport on departure thankfully, but I'm a bit concerned that one day we'll be about to leave the Philippines after a holiday and suddenly have a lot of hassle.....
Leaving the Philippines as a tourist can also be a nightmare too...
