The only evidence or connection I remember between SAD and the Philippines, from reading on FR, is some kind of (curse my bad memory) - a visa application, or some kind of passport form - and mention of a Philippines visit, but IIRC it was proposed, not necessarily accomplished. My memory is just not serving me well.
I’ve got the article bookmarked on my old laptop and I posted it here a couple years ago, but I’m going to search for it.
