So I just used my APEC card for the first time traveling internationally.
Hong Kong (No Problem)
Chiang Mai Thailand: The immigration person said something about the lack of stamp on back and next time use normal line but let me through
Clark Airport Philippines: The agent said i shouldn't use the lane since it wasn't stamped on the back. I countered that I was told that was ONLY if a visa was required to enter a country, if visa not required which it wasn't it wouldn't be stamped. She did let me go but but unsure if she believed me.
I read there are mixed results in the WIKI. Does anyone have specific documentation or something you can carry to explain to the person at immigration that being stamped is not required? I may use google translate and print and bring it with me for future trips
