I arrived here from Singapore at NAIA on 23rd August 2014. My South African passport allowed me to get a 30 days visa stamped in my passport on arrival at no cost. Immigration officer only asked when's my departure date (22 Sept). I had an outbound flight ticket from Manila to Singapore (Jetstar) purchased online before departure from South Africa.
At Cape Town International airport I was refused to proceed to pass through to departure lounge because I had a one way ticket on Singapore Airlines to Manila via Singapore. I had to purchase a return flight ticket there (US$500) added to my one way ticket, so that I could be allowed to board my flight from South Africa. Travellers beware; most airlines refuse boarding if you don't have a return ticket back to your country of origin.
On the 18th of September I travelled (by tricycle, jeepney, 2 busses & jeepney rides) from Canlubang, Calamba, Laguna (where I am currently staying) to Bureau of Immigration in Intramuros, Manila for my first visa extension cost = PHP3,130. Thereafter I can extend for 2 months or six months every time for up to 36 months, Immigration Officer told me.
Anyone is welcome to contact me for further information/advice
