Search on the forum. LFT - this has been discussed before. You are STILL flying under IFR on a visual approach UNLESS you 'CANCEL IFR' with ATC. Theoretically thus the g/a would be for the IFR approach in use. Practically a chat with ATC will determine what you can do. Normally into the circuit would be fine UNLESS there is other IFR traffic in which case you would need to either fly the IFR g/a OR follow ATC directions. I do not think this is specifically determined in 'pilot' writing, however, but it may be in some ATC manual.
