Hiya this is a simple choice for you Option 1, do nothing and when you arrive in Phills you will get a 30 day visa free stay, which you will have to extend for a further 30 days i think it is, at the nearest BI to wherever you are staying, ie Manila, Cebu, Davao etc etc. Option 2; you can apply to the Philippine embassy in London either in person or by post, simply download the forms from the website, http://www.londonpe.dfa.gov.ph/ and follow the instructions, this will give you a 59 day stay for the princely sum of £24, thats where my Passport is right now i just missed out on a minor detail and have posted said omission off only today. so theres really not a choice its Option 2 that i reccomend.. no hassle.. enjoy your stay.
