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.
As a US passport holder you don't need a visa for the UK, unless you have a criminal record or have previously been refused entry to the UK. The General Visitor Visa page tells you how to apply for one if you need one. It doesn't mean everybody needs one.
