It seems most do the IAP, in my limited experience. Remember the airport might be Class G, but Oakland OAC, if there is a traffic conflict, issue holding, then issue the guy at the bottom of the stack a cruise clearance which is the permission to leave controlled airspace and fly the approach. I can't see any reason why one couldn't fly a visual, weather is usually VFR.
Palau, Yap, Pohnpei, last the "real"flying
