When traveling it is absolutely necessary to travel with passport photos. Professional Passport photos. The whole “I’m gonna print them off my computer and save me a dollar” photos will not work when trying to pass through immigration. Therefore I suggest you shell out 50 HKD for 12 photos.
And don’t forget not to smile. Seriously. My photographer was hysterical. I smiled. He said, “No teeth”. So I tried not to smile. And then he told me to smile a little hahah. Make sure it’s a white background. Conservative. Appropriate. #HAIRinBUNisaJOKE
