The USA Visa Waiver green slip is still in my passport. I believe this means the government have no record of me leaving the states & thus will not let me back in. What can I do to have this QUICKLY rectified?
Me too. Just back and the green waiver from my last visit was still stapled to my passport. Still is, they just took the new one. I doubt you will have a problem.
The same thing happenend to me with regrads to still retaining the green slip
I then was going to New York from Shannon a year later.
When I was going through pre-clearance immigration in Shannon I kid you not the guy said to me that as far as he was concerned I never left America.
I got read the riot act and told it was my responsibility to get it back to the government and if I did it again he would have to seriously consider my next stay!
