Hello all!

I have several unused visas in my passport that have since expired (plans change a lot!)... They are for:

-Jordan
-Syria
-Uganda
-Vietnam

I have never had a problem with them until this last weekend when I flew into YYC and the Canadian officer put me through secondary immigration screening because of them (I have a US Passport). Then the US officer on the return also gave me secondary (The Canadian officer scribbled something on my stamp -- "V-4-10-08/2C/Q") I am guessing the 4-10-08 is the date I must leave by since it is excatly 6 mos from my arrival date of 4-4-08). I am wondering if this was some code for the US officer to give me the secondary as well. The US officer looked at my Syrian visa and asked why I never used it. I told him the truth that I was going to go, but plans changed last minute. He also questions me about the Vietnam visa (but not the Jordian visa). He said "why would you want to go to Vietnam? You are too young to have been in the war. No one would want to go to Vietnam for fun." He told me that I should not have unused visas that are expired. He said it could render my passport "useless and invalid."

Has anyone else had any experience with being questioned about unused and/or expired visas?

Thanks!
