IO540, to answer your question above, you can file an IFR flight plan, fly from A to B and request a visual approach (min. vis. 800m) or be asked to report when ready for visial. By making a visual approach you are NOT cancelling your IFR plan and continuing VFR, you are just making the approach and landing using visual cues, in transport category aircraft also usually using DME etc to monitor progress.
