I got my passport when I was 16 years old and I had really long hair. I've never been denied entry, but It has been 8 years now, and I don't look 100% the same, and my hair is a lot shorter now. I've been looked at funny when crossing the border into European nations, back into the US, and through Canada, but haven't had an experience where I couldn't explain that it is a really old picture, because everybody has spoken English. I'm not sure if this might be a problem while coming into Bangkok, Cambodia, or Vietnam. I'm not sure how many of them speak English fluently. Has anyone had a problem with this? I'm leaving in 4 days.
