Hi there. Coming to Spain very soon. I am studying Spanish for a few months so coming on a student visa. I want to then follow that up with a digital nomad visa. And therein lies the rub. I see people online no problem. But I am self-employed, sole trader and clients pay directly to my account. If I have understood the DNV rules correctly, I need to be working for a company that I invoice that then write a letter to say they are happy for me to provide the service from Spain. Is that right? Wrong? If it's right is there a work around? Any info gratefully received. Thank you
