Sorry about sounding like I take arrest lightly. I absolutely DO NOT, if I did something wrong. The thing is though that I wouldn't have done anything wrong, so although unpleasant for the time being, it probably would not be that big of a problem in the end. What would happen though? I am just basing that upon what I think, not what I know, so if you are familiar with what happens when you are detained by customs in Europe or countries like Singapore or China (Hong Kong area, not normal part) I know I would have to clear customs in ATL, if that was where I reentered the US. That is the only airport I can remember entering the US in. The three of my trips to Europe had the flights from Europe to ATL. The other customs time was when I was four weeks old and that was in MIA coming from the Turks and Caicos. I obviously don't remember that. One year ago, I took a trip to Greece and flew SR through ZRH. I didn't have to do any customs either way, just security, but nothing more. During this summer, I went on a school trip to Spain and France and we flew to BCN through LGW and I only had to go through security in LGW as well. I flew back nonstop from CDG and the first time I went to Europe was to BRU, and both of those flights were nonstop (ATL-BRU-ATL). I was just thinking, that depending on the countries visited, it might just be that procedure until I arrived in the US again. I probably sound very teenagerly like in this post; sorry. Thank you so much though for your help!
