Hi there, welcome to the forum

.
In short, I simply just want to pack up everything and go on my own and root in the UK for no good reason other than to just be there and enjoy the change of scenery. I've always sort of been fascinated by the culture itself and the architecture doesn't hurt either.
Perhaps I'm pursuing it for all of the wrong reasons, I have no idea. But I'd love to hear what others have to offer in terms of where to begin with this newfound theory that I should eventually (hopefully sooner rather than later) make my way overseas and settle in.
I don't think those are the wrong reasons at all

The thing you'll need to overcome is that it is not easy to move to the UK just because you want to experience the culture - you need to be able to qualify for a visa in order to move there (sorry wrote this part just before you posted your second reply

).
If you don't have a UK citizen fiance or spouse, then your longer-term visa options are basically limited to a work visa or a student visa.
- Work visas are becoming increasingly more difficult to get... you would need to get sponsored by a UK company, but if your job field is not extremely specialised or highly-skilled, the company has to prove they have search the UK and all other 27 EU countries and not found anyone suitable before they can hire you.
- Student visas are not that difficult to get, and you could maybe go to grad school in the UK, but you do need to have enough money (either your money or a US loan) to cover one year of tuition and one year of living expenses in order to get the visa (about $25,000).
A couple of other, more short-term options for you might be to see if you can do a study abroad semester or year in the UK through your current university in the US - I did a study abroad year in the US during my UK undergraduate degree and it was the best year of my life

Also there is the BUNAC Intern in Britain scheme for college students/recent graduates, which would allow you to live in the UK for 6 months while doing a pre-arranged internship (
