my friend just had her police clearance here in qatar. she went to phil for 2 weeks holiday. she went to NBI to renew her NBI clearance and authenticate it (red ribbon) then when she got back here. she went to CID dept. to apply for police clearance.i sure it is quite same in phils. try to go to your local police station and ask about it. and i am sure they will assist you through the process.
