In the Philippines you have 30 days in the country without having to obtain a visa. If you want to extend this there are a few ways in which you can do this.
Visa extensions add an extra 30 days onto your passport.
Immigration offices are located all over the country with the main ones being in Manila and Cebu. The only issue with these offices are that they are very busy and it takes a few days for your visa to be extended. We got our visa extended in 20 minutes in the Bohol office.
In Bohol immigration office we purchased the express visa extension, which cost us 3130 peso per person (£45). We had to wait 15 minutes and it was all processed and we continued on with our day.
