I’d totally go for it. I moved to Europe at 30 and it was amazing. Just a few things to think about:

it’s very hard at first and lonely even if you know the language, be prepared for that and don’t feel like you’ve failed or anything if you feel unhappy at times

Keep in mind what happens if you want to stay permanently- I originally moved for 1 year and ended up now permanently in Europe because I love it and I fell in love with someone here. However it has a big effect - like I’m very far from my family, my retirement now is a mess, investment is complicated because I have assets still in the US, etc. All manageable stuff but just be prepared

Also in terms of staying longer - be clear on what your visa allows and if you can renew and if there is the possibility to convert to long term residency.

No. You would have had to live with him as a minor in the UK for him to sponsor your residency which could have transform to citizenship if it met all the criteria.

Do you speak any other language and do you want to be able to stay/work after graduation?

Scottish married to a French living in France. It’s hard at times. My kids are bilingual so far but still young, I want to make sure they can natively read and write English with a high level, I’m not sure how at the moment because most bilingual schools are way too expensive. All my family now lives in the US too (and I spent a lot of time there), so it’s a bit mixed in terms of cultures

Totally different places and depends entirely on what you want…

First of all, bad person? You want what you want and you don’t owe your happiness or health to a job. So don’t think of it in that terms

Then as an immigrant myself with an organization that hired a lot internationals, it’s really common for people not to want to stay or be unhappy with an international move. It’s hard to know if you’ll like a place and it’s a lot harder than most people expect to change countries.

Anyway, I’d just re look at your contract, sometimes you have to pay back moving expenses if you don’t stay x amount of months, things like that, but they will be explicitly stated if it’s the case.

All that said, I know for the first 6 months I really struggled with my new city but after that I really loved where I lived and my new country. So I’d consider if maybe you are just temporarily unhappy because so much has changed. Not to stay you must stick it out but it’s something to consider, I don’t think the first few months are easy for anyone
