I know it's not pedantic. It's essential people know if they have a visa or not. If anyone wanting exempt entry and heads to "visa on arrival" they will be refused.
well I don't know many cash strapped folk who pay thousands for holidays but can't find 20k cash to bring with them. Just because I don't agree that the equivalent of about £475 isn't a lot of money for starting a holiday does not mean I don't understand the value of money. What a dopey thing to say.
no need to redo maths. 20k doesn't last long. They aren't asking for evidence you can fund the whole trip. It's not much different to arriving in USA and being asked to show money, as I was asked to do few months ago.
