Make a plan.... with dates.
Organise your documents.
Book appointment slot at the Embassy in Manila to coincide with your arrival best as possible.
Organise the wedding date early. Important as sometimes it's tricky to find someone available for the wedding.

30 days should be plenty.....but do have a prepared plan and a check list.

Double check each and every document for any errors and spelling mistakes at the time of issue and get corrections made at that time.
