Well, I have a multiple entry visa valid for 6 months with period of stay of 180 days. So basically, doesn't matter if entered the UK 4 times a month, my duration of stay would never exceed 180 days.

And I didn't get my visa stamped when I left UK! It's kinda weird.

Thanks guys. But a friend of mine said that she did not get another stamp, other than the one she got from her first entry. This is really confusing.

I'm currently holding a UK tourist/visit visa expired in March 2010. I stayed there for a month last October, and planning on visiting UK again. My question is, would my visa receive another stamp on it? Or will there be only one stamp, i.e. the first day on entry?

Thank you.
