I applied in UK just showed balance at time of application. No more. For work I showed contract with company (which stated remote) and payments made by them.
Anonymous participant ok. I do the same. I applied via UK. I consult and have a couple of non execs. But I also set up a business to invoice them, and have a contract with one of them. I had to provide them as evidence that I was working remotely. I imagine you will need to do the same else anyone could say they are working remotely etc etc. sorry, probably not want you want to here
