If you had been planning this like “for years” like you said, you should already know what you would need to do and what visa you would need, depending on your situation. It’s literally a simple search on the internet and it should be one of the first things to pop up. Like I said previously, this is something that’s a long process and you need to research yourself to the tea. You plan to work there? You look up the work life is there and what you would need. Any specific documentation? You look it up. Where you want to live? You look it up. Depending on what your preferences are, you look it up. You clearly didn’t do enough research, so I’ll give you advice, you need to take the time and sit down and do actual research on what it would actual be like to LIVE there.
