A bit off-topic, but it reminded me of something. I happened to give a speech in Karachi, Pakistan a few years ago. In order to get there, you need a visa, which takes up a full page in my passport (you can't miss it). I certainly have been asked about it before a few times but now I am wondering if that is going to "haunt" me for a while. Coincidentally, I have an ORD-CDG trip this Thursday, so I will see how ORD and CDG security will react to it.
