I am an American trying to get a tourist visa but I am confused. The UK visa and immigration says that I do not need a visa for a 180 day (6 month) visit, but the General visa description says that I have to pay 83 pounds for the application. I don't understand what's going on and immigration services are impossible to get in contact with. Do I need to still pay for a visa when the clearly say that I do not need one? I am from the US and I am looking at the UK visa and immigration site.
