It's more like "formality" than anything else. They will grant your COC unless maybe may criminal record ka sa Singapore or under some terrorist watchlist. I find it funny that they call it an appeal. Oh well, semantics I guess. like when they say "form of international cooperation" what they meant is reprisal. Ipitin nyo COC for our citizens at iipitin namin ang NBI Clearance ng citizens nyo.
