I moved last year to Japan. Had a job sponsor before I moved and I think thats the only way I could have done it at the time. Luckily the job sponsor was not attached to my visa so I was free to change my job. My advice after 1 year abroad is try to be as open as possible, try your best to forget how it was in the UK cause youll always be comparing it. Moving abroad will make your life at least twice as hard as it was in the UK, because you will have to learn a new language and your whole livelihood depends on it. Be open, try to make friends, learn who is worth it and who is not and get lucky with your job. The hardest problem for me has been keeping my mind in check and focusing on why im here and long term goals.
