@yapjaman you just need to file for a "visitor's visa" for her at kung meron ibang isasama like ibang family members, same thing... you can google it and you'll find info on how to do that.
visitor's visa will be valid for 3 months lang as far as i am aware, if you want it for 1 year, she will need to do some health tests from an accredited clinic in the philippines, sa makati meron i believe so, mas tedious nga lang...
hope i was able to answer your enquiry mate đŸ™‚
