You need to make an appointment... Depending on where you will be, it can be in Manila or Cebu.
Regarding the 21 day thing, i'll need to think back 2 years ... (and for me i was there for a month before the wedding anyway - and a further 11 after it) ....

You should budget generously with your time as well!
