Hi Priscilla;
Depends on what you are really saying <G>... We do have a circling approach but that is for when you are on an IFR procedure ie; VOR or ILS and want to land on other than the runway that the approach is being made to. In that case, there are circling minimums that you must meet to do it.
If you are just wanting to move over to a parallel runway while on a visual approach then that is known as a sidestep here. If you want vectors to the initial for the overhead, that is where you are IFR (normally) and get vectored or do your own navigation to a point about five miles straight in to the airport. Upon reaching that point called the Initial, you are no longer IFR but VFR. You continue straight in at the airport normally about 500 feet above the pattern altitude (different at different airports) and then fly over the runway and make a turn into the down wind where the tower instructs you too. This is known as the overhead to the break and is normally done by the military and some who fly old war birds. Or some like myself who just miss flying old war birds <G>...
Hope that this helps some.
