I travel overseas frequently on business trips and have never had any problems at the airport before. I just came back from another trip to Asia recently. When I was waiting in line, I noticed that the officer in this line seemed to be new and frequently asked the other officer in front of her questions. When I gave her my passport and green card, I was surprised to see that she swiped my passport instead of my green card. Then she looked at the monitor for a short while and asked the other officer if she should send me to secondary inspection. I was wondering how the other officer could know since he did not inspect me. Since she did not get an answer immediately while the other officer was busy, she gave me back my documents and asked me to go to secondary inspection. She did not even look at my green card during this one minute. I went into the secondary inspection and waited for a few minutes before an officer picked up my documents and worked on his computer for a while. Then he called my name and asked if I live and work here. Then he typed something into his computer for a while and let me go. I asked him why I was sent there and he said somebody else's name was close to mine. I then asked if I would have problems in the future and he said I shouldn't. He said the first officer was probably not sure. The officer was quite polite during the process. The whole thing seemed strange to me as I had never been in secondary inspection before. I am still concerned if I will go through the same thing again in the future since obviously now I have something unusual in my record. I hope the officer clarified things in their system. I am wondering if someone here had similar experience and what was the POE experience after that. Thanks.
