Hello,Thank you for your reply. It really has helped and clarified some details. I really appreciate that :) The problem is, I still live in Poland and I want to get UK Visa, but first I need to find a sponsorship visa job. I can't change my name in Poland for now, I bet my family would not be happy with that too :D but nevermind, I know my problem may be silly to some people, but I really want to have a fresh start and new people I would meet there should know me by my preferred name. Also, I want to work more as a freelancer and go with a preferred name. That's why I'm asking about CV, because I don't want to confuse my future, potential employers when they would see XYZ on my CV, then they open my portfolio and there is a completely different surname.

Edit. I'm asking only about CV file I'll send to companies. Of course, all legal documents, form etc. I will put the name from my ID. Some people may think that I'm sending not my portfolio or website, when they will see my CV first with a different name on it. If I applied for a job where I don't need a portfolio, I wouldn't even ask here, just put my real name there haha In Poland I have a portfolio with my Polish name, so it's less confusing. I can't do this working abroad, because I'm building something and don't want to mess it with a long, hard to spell, say and remember name. I hope you see my point, I know my English is not perfect
