Honestly, I used to come to the UK once a year, for a very long while, because from the first time I came to London it felt like home. Always wanted to live and work here. So I finally decided to bite the bullet, went through the visa process to make it happen, and here I am.
Do you like it here? I can't imagine why anyone would swap the US for the UK these days (especially in the last 10 years) but I hope you're happy and welcome to the UK.
