been today for my annual retirement visa at CW the only thing that changed that they wanted to see the house book and the owner (in person), luckily the wife was with me, so it was just photo copying and her signing also the TM 30. This the very first time i have been asked for these in 6 years, if we didnt have them it would have been a trip back home.
Also i did book a time which worked out well, one other get your documents checked before seeing the official first on the right as you go into L area.
One more thing if you are driving yourself its a nightmare to park as they have closed the main areas for parking, easier to get a taxi or a motorcycle taxi.
