Visa waiver card left in passport

Hi - hoping someone can put my mind at rest. Last time I travelled to USA was 2 years ago. When I got home I realised that the bods at immigration in LAX did not remove the green visa waiver card from my passport. Does this mean their records will think that I have not left the USA?

Has this happened to anyone else?

I still have the green form (kept it safe all this time!) and I also have a China visa in my passport subsequent to my stay in the USA so it should be easy to prove I actually left the USA 2 years ago. But I am going back to USA this summer and the last thing I want is hassle on arrival at immigration.
Any advice gratefully received.
Cheers
Flo

You are not the first. Please have a look at this discussion, and this older one which may help.

Thanks Nick
I did a search before I posted but I didn't use the right key words!
Very helpful advice - as usual.
Many thanks

As Nick says, and I can testify, many people find them, lose them - and have no ensuing issue. Simply implies how inefficient extreme bureaucracy can be - however necessary it is.

No worries :D

Searching in V-Flyer is a bit hit and miss right now, thanks to our overloaded and over worked server.

Pixuk has done a great job getting us back up and running after the spate of error 500 messages.

Searching the database is a very resource hungry activity, so it is best just to search in the title of the thread - for the moment at least.
