My question was....the cost of having visa extended at airport ....as stated in quote by steve r......we normally have it done at the Swagman in Mabini, the downside going there is we have to come back at a later date to collect the passports.
Obviously more convenient doing it at airport.
Btw Swagman also take card....we always get peso's in Manila we just a few to pay for taxi....hence wanting to know how much airport customs want for the stamp
