If you are wanting to extend your visa, I suggest you get to the Bureau of Immigration when it opens at usually 7am. The reason being is that I have had the misfortune at getting there early, midday and late and each time I have paid different amounts. A Visa extension should cost you no more than PH4000 or you would expect from reading their website. Wrong!! Get there at 7am and you will pay PH3,800 waiting time is approx 45 minutes Get there at 12pm and you will find that you may probably pay almost PH5,000 waiting time is approx 2 hours Get there at 4pm and the price increases more to almost PH6,000 and you may be told to come back the next day If it is your first time there, you will issued a ID card at a cost to yourself. Get there at 7am and the price including the ID card is about PH4,500 waiting time is approx 1 hour. Get there at 12pm and the price goes up to PH8,000 waiting time approx 2.5 hours or more Get there at 4pm and the price is the same as you would pay at getting there at 12pm, and you may be told to come back the next day. I have never paid the same amount each time I go there! Also ensure if you stay in the Philippines for more than 6 months you will need to go back to the Bureau of Immigration 1 week before you leave to get Immigration clearance. failing to do so, will render you unable to get your flight back home. I am not sure how much that will cost either!
