I tried to get a term life policy before leaving Canada, all was well until they asked me to fill out a travel form. Once they found out I was going to the Philippines for a length period of time, the refused to insure me.
I would certainly check with your agent in US. Most companies consider living in the Philippines dangerous and don\'t want to insure you if you are there for anything more than a 3 or 4 week vacation.
I did find a company in Manila, Sun Life that will issue a life policy but it is actually very expensive. I was quoted P20,000 for one year for a one million peso policy.
Hope this helps.
