Hi,
My wife left the country today to visit family, and when she called to let me know she arrived safely, she mentioned that everyone leaving was interrogated before being allowed in the boarding area by some U.S. customs or immigration officials. She was asked how much money she had. Where she was going/why/how long. How long had she been here. When did they start this? Next they are going to want DNA samples and 10 years of tax returns. Every country I have been to basically says "Welcome to <insert country here>, enjoy your stay". It has always been a pain to return to the US and go through customs, but now you can't even leave the U.S. without being harassed?
