This is not a new process. It's been going on since then. Check their website for more info.

Anyway, send the NBI clearance to your relatives who can help you out there in the Philippines. Let them go to DFA for the authentication. Enclose your letter of authorization also. The stamping can be done in the Qatar Embassy there. Just coordinate with Air21/Fedex to do that for you. The embassy does not allow personal appearance.

Then, after the process, ask your relatives to send the document back to you. Got it?
