No matter what country you are from, you shouldn't offer your hand to the queen to shake. Instead, you should wait for her to offer her hand to you, and then you should give her a very brief (and not too firm) shake. Aside from this handshake, there should be no touching of the queen at all — remember when everyone freaked out about First Lady Michelle Obama placing her hand on the queen's back? By the way, this goes for all members of the royal family, so save that hug that you've been dying to give to Kate Middleton for a different time.
