I'm just jumping lately on this, but all the foreign Embassies knows this as it's required by Philippines laws. When I inquired first at French Embassy to get a Fiancé visa for my now wife, it was indicated in the package of documents to get for the visa with addresses (including opening hours and web site) where to get the CFO seminar. I just asked some complementary informations from the Consul Secretary, so I had the full infos when I got the papers to fill-in for the visa request.
The British Embassy didn't warn you about it?
