Be careful.
Whilst I am NOT saying anything bad about Omni, they are one of the better of a bad bunch there, your licence will be a CAAP issued ( Civil Aviation Authority of the Philippines).
Remember that (with the exception of PAL and 5J due to their own efforts) ALL PHILIPPINE OPERATORS are still on the EUROPEAN BANNED LIST-
Many airlines wont accept a CAAP issued licence. You may be limiting yourself to employment options.
I have heard so many stories of logbook padding, things like 5 people in a Cessna 172- all logging it as P1 time etc etc that many airlines are cautious of pilots trained there, and many authorities wont recognise it.
Always better with a FAA or EASA licence.
