Abra,
>>Don't forget that in the States,if you accept a visual approach and have to go around,the proceedure you follow is a visual one and not the standard missed approach.You have also thrown away your ATC IFR flight plan alternate.<<
You are mistaken, if you are on a visual approach, and for some reason have to go around you are still considered as an active IFR aircraft.
At a towered airport the control tower will issue instructions, these can be either a heading and a altitude to go back to the radar approach control for resequencing, or to enter the local traffic pattern, either way you are still on an IFR Flight Plan.
At a non towered airport, I must still protect the airspace around that airport until you cancel your IFR flight plan. IFR pilots for some reason think that since they are on an IFR flight plan that they are number one to the runway, this thinking is wrong, and dangerous. You must take in consideration any local traffic.
As for having thrown away your IFR alternate on a visual approach, the only reason for your need for the alternate is if the runway/s at your airport of intended landing closed unexpectedly, again all you would have to do is contact ATC and notify us of the problem.
