I'm a UK Citizen, filmmaker, travelling to the USA to visit a conference and do some filming of the event to add to some videos I'm making for the client back in the UK. It's a UK Based client.
Does that count as business so I can use an ESTA, Visa Waiver? Or do I need to get a specific visa for this? I'm only going to be filming for a couple of days and not getting paid for the filming, It's to add to the edits I’m doing in the UK which I'm obviously being paid for. Does this count as business? It's all a little confusing? If it helps I'm indulging in tourism after the event for a few days so my trip is a mixture of business and pleasure. I just don't want to arrive at the airport with my cameras and be told I'm actually in need of a visa.
Anyone with any experience or advice, I'd appreciate your input.
