As you are contemplating to go in the Philippines for 2012 ASDAL Conference, you may now consider this visa information. I got the first question from our friend in our university in Jamaica concerning this. I immediately consulted our liaison officer and he advised me to ask the participants to inquire from Philippine embassy in your country if our government requires you of visa going to the Philippines.
As I also search from our government website, I got the information below which was posted in June 26, 2009. I am not sure if this is outdated information but to be safe, please check with the Philippine embassy in your country. If it happens that you need visa, AIIAS is very willing to send you an invitation letter.
