Unless you already have arranged for a Retirement visa, an Investment visa or Permanent resident status, your first interaction with the Philippine immigration department could be at Manila airport. You will be allowed an initial thirty day visitors visa. Then can be extended to fifty nine days after which you need to make additional arrangements.
The easy part is getting a tourist visa. You need no assistance with that until you stay here beyond fifty nine days. Please don’t even think about getting any long term visa or residency status without the assistance of a competent immigration attorney. This area of law is complex and needs to be treated accordingly.
