You need Barangay Clearance as well. NBI have a habit of putting a hit on your name, that means someone with a name like yours has been a naughty boy, so they will investigate you and charge you a few thousand for doing it.

They did it to me, and it took 5 weeks to clear. Had to appear in front of a lawyer and, as it turned out, the guy's name was nothing like mine. Got my NBI one day before my appointment with Immigration.
