Can I move to Seoul from UK?

Hello, I am currently living in the UK and I am considering relocating to Seoul. Could you please advise me on the process and requirements for moving to South Korea? I am particularly interested in understanding the visa requirements, job opportunities, and the general cost of living in Seoul. Additionally, I would like to know if there are any specific cultural or lifestyle adjustments that I should be aware of before making the move. Thank you for your help!
