I visited Hongkong club in April this year and reentering US from Tijuana was a bit scary. The officer asked me what did I do in Tijuana. I wasn't sure if I can tell him the real reason (Clearly a club like HK would be illegal in US). So I just said I came to Tijuana just to check it out since I've never been to Mexico (I know it's very lame :)) .the officer clearly didn't buy my argument and asked me to show my backpack. He asked with a smirk on his face I went to HongKong..I wasn't sure if I should say yes. I said No. He again didn't buy it. After a couple of more scary minutes, he let me into the US.
Clearly I wasn't prepared for this.
My question to everyone is, what reason do you give the officer when reentering US from Tijuana ?
Note that I am not a US citizen but am a GreenCard holder. Not sure if it makes any difference. Also I do not have any enhanced ID to enter sentri or fast lanes.


I think you are worried about nothing. But as you say you are a Green Card holder and you may have more to consider? In my experience most border officials are ass holes, not all of them though.
And while it is really not any business of the USA what you do in another country, border officials rarely like to admit that fact. The old cliche question is whether you were there for business or pleasure. Not sure if they still ask that or not.
But bottom line you can always tell them you were visiting friends. They don't necessarily need to know they were new friends or strippers.
