Sevenstrokeroll got it right in his reply...
Realistically, I would just enter the pattern and land, if I was being vectored around then when I'm cleared for a visual I get that little addendum to my clearance which says "radar service terminated", so I'm on my own for all intents and purposes unless I choose to get "radar service" again. On the other hand most of the other places I fly have no "controlling agency", in a practical sense, we simply get a cruise clearance to the airport and told to call on the ground.
