How much is the Overstaying Fee for Tourists in the Philippines?

I think as a rule of thumb for any traveller staying in any country, don't show up at the airport with an expired visa. And don't throw a fit if they won't clear you for your flight. If you had time to overstay, you could at least endure a day in queue at the Bureau of Immigration.

Yes, they have a counter at the airport that deals with overstaying tourists. But NAIA doesn't want to encourage this among tourists. Overstaying shouldn't be taken lightly. In other countries, overstayers are detained then deported.

As of March 2010, a balikbayan friend of mine paid P2,500 for a 30 day overstay.

The penalty for overstaying is P500 per month plus extension fees which usually adds up to P2,520. The common figure I encountered when I ask overstayers, the ones who are drunk as shit in Boracay and the last thing they could care about are their passports.

Travellers can pay up at the immigration counter in NAIA on the day of their flight. A risky move and if you have insufficient funds they will not allow you to board your flight. Its a no pay, no flight policy.

So save yourself from the stress and get a proper extension at the Immigration office.
