I actually had girls approaching me, one of which I still talk to.
However, in London software engineers don't make all that much money.
But... Hell yes, you should try living in another country! Life is too short to be stuck in one spot.
Plus your a hop away from the rest of Europe, explore, see things. Visit old castles.
I've yet to find a company that's willing to let me work remote from Europe.
I guess I could do a corp2corp LLC with a mailbox in my home state, but I've never done that
Unless you have a work permit in the foreign country you are either working illegally (enforcement close to nil, say you are a tourist when entering) or you have a long-stay visa that allows remote work — many countries offer such visas now. This is the digital nomad thing.
Another route is freelancing. You just keep your US bank accounts and set up a mailbox, line up clients.
I did this for six years and not one client cared where I was as long as I answered emails and phone calls promptly. I started traveling when I had a f/t remote job, I just started traveling, no one asked or cared.
If bad weather and high cost of living rank high on your list of desirable attributes, London has those. I wouldn’t wave “visa issues aside,” either. UK long-stay visas are hard to get. Maybe visit for a couple of months and decide for yourself instead of asking for random and meaningless opinions. I (American) lived in England for two years, it’s not on my list of places I would choose to live again, but everyone has their own criteria and opinions.
