Mrs T travels on a B2 Visa. We were just sorting the details for our trip next month and discovered the I94W still in her passport. The 6 months cut off from her last trip is up in a few days.

Has anyone any experience of what happens when you come to immigration with the I94 from your previous trip still in the passport? We could try sending it off to the address shown on the website (Kentucky), but given that we are travelling in four weeks, I doubt its return will be registered in time for our next trip through immigration.
