Ordinarily, Indian citizens requires a visa in advance for the Philippines but if she has a valid Australian, Canadian, Japanese, Singapore, Schengen, UK, U.S. visa or permanent residence permit then they can visit for a duration of 14 days.
I recently tried this by stopping over in Manila for some meetings (yes, you can get both tourism as well as business entry) on my Taiwan to Singapore trip. The process was fast – I joined the regular immigration queue. The officer made sure that I have a valid visa issued by one of the above countries and proceeded to stamp my passport.
Below are the two forms you will have to fill. The Disembarkation Card and the Customs Declaration Form.
