I have recently taken a job with an American based company and will need to complete a few weeks training in Miami. Based on the information they have given me I need a B1 visa and maybe an ESTA since I'm in the UK, and a C-1/D for moving through the US.
However they keep flip flopping between me needing a B1 and me just using my ESTA for the training, and their communication hasn't been the most straight forward. Which visa do I need to get to enter the US for the training?
