Whilst Singapore passport holders enjoy visa free access to many countries, I still recommend applying for an APEC card.

Not only does it gives you visa free access to 14 countries, more importantly, this card will allow you access the priority/special immigration lanes which makes crossing borders a breeze.
The PRC, Hong Kong, Thailand, Vietnam, Indonesia, Philippines etc - where the lines can be so exasperating, but the best is when I go straight to the Aircrew special counter when entering the United States!
Also, I've never encountered any problems ever since I started using this card as the immigration officers knows that APEC card holders are frequent travelers - and thus not easily "shaken down."
