Here is what i could figure out and it looks like i can transits/Hang out without visa in UK:
---- Notes from UK Border Agency website -----
Additionally, if you are a national of country covered by the DATV system, you (or a person with whom you arrive in the UK) must hold:
1) a valid entry visa for Australia, Canada, New Zealand or the USA, and a valid airline ticket for travel via the UK, as part of a journey to or from one of those countries.
------------------------
Since, i have a valid US visa... is that all i need and i am fine? How do i confirm that this is good and i won't need anything extra?
