Pros.

it runs really differently to the US, so you may find some things easier here. Taxes work differently- a shop price is what you pay, there's no extra to fork out. Taxes are taken out of your wages before you get your salary, too. You may have a good pension plan, too, which is done for you (you can opt out if you wish). Some things are digitised here which aren't in the US- like driving licences- after 1 year you'll need one.

There's more contactless payments, inc on phones, apparently, and if you use a card, you'll need a chip and pin one- which is safer. Con???- no drive in banks or pharmacies here.

Work culture's very different- (tho not sure what your job is). its ok to take lunch, and you'll get more time off- 4 weeks paid leave (sometimes more), paid sick leave, and if you have kids you get paid maternity leave of nearly a year, and some paid paternity leave- or can share that leave between the two parents (inc same sex parents). If you adopt, that's free, and you can get paid leave for that too.

Work contracts work differently: its far, far harder to fire someone here, so people feel more secure in their jobs. Free healthcare means people aren't giving their life to work, either. "Better work life balance" comes up as being popular with Americans over here, compared to the US. The chance of getting a work visa has significantly increased for you with Brexit, and the whole thing's been streamlined, too. We have tight anti discrimination laws- LGBT, race, disability- that shit still happens sometimes, but we try to stop it.

No dangerous animals or plants (eg poison ivy), no dangerous weather, and no real extremes either. Most of the winter's above freezing in southern England.

farming's differnt- higher animal welfare, fewer chemicals. About to start massive investment in green economy, adn more eco farming methods.

Culturally, the entire UK is far to the left of the US- which was true even under Obama. Election cycles last up to 6 weeks, and are strictly controlled with spending caps etc, meaning its easier to avoid politics if you want to. Inter- racial relationships are no big deal, and pretty common. there's less racism, and race isnt the big deal it can be in the uS.

There's no religious areas; the country's pretty secular, anyway. Those who are religious keep it relatively quiet, and there's little to no dent in daily life from religion. No large areas are conservative in the same way either- you'll get the odd, small wealthy enclave, or the odd small area which is more right leaning, but even that's still to the right of the US- so its still not really the same thing- i grew up in the countryside, fwiw.

So stuff like abortion isnt controversial. I know there's some states (eg CA), and plenty of areas within otherwise conservative states (eg Austin) which are pretty liberal- but the UK as a whole is liberal generally, and on this kind of thing specifically. Contraception isnt an issue- no one cares. Obviously, with universal (and free healthcare), condoms, the pill, the coil, abortion, and sterilisation are all free anyway. No dramas.

Cost of living's hard to know. I watched some "culture shock" videos on yt recently, and Americans generally found groceries cheaper here (and "fresher" too- taste wise, but also complained they went off faster- you guys put preservatives on fruit etc??). Eating out often costs more. I dont know about the rest of it.

Socially, we're very differnet- which may be a pro or a con- less enthusiastic, more low key, often more humerous and sarcastic ("banter"), and humour works differently too.

You may feel safer, depending on where youve come from. Obviously much of the rural US is pretty safe- but here no one keeps a gun "just in case"- cos they're super hard to buy, and its a massive deal. I know its an emotive subject for Americans, but to people outside the US, guns are pretty terrifying- even in the hands/ ownership of someone "responsible". There's gun clubs and owners, but no lobby aimed at loosening tight gun laws.

Villages, and isolated farms etc, are laid out differently to the US, too; so here, an isolated house or farm is usually near or on the main road, whereas in the US, you seem to have a lot of places with long drives, way off the main road. So here, even if your nearest neighbour's half a mile away, they might still feel a little closer, cos you won't be walking up a spooky long drive to their place.

Unemployment's impossible to gauge, cos there's a recession etc etc and who knows with covid. Its better than much of Europe, though- Spain, Italy, adn much of Eastern Europe are far worse off.

The UK's obviously in Europe, so you can reach France, Spain, Italy, Sweden for $10 each way on budget flights, flights are 1.5 to France, or 2-3.5 hours to the rest. Massive bragging rights for social media if you want to piss off mates back home- you + castle, you + Paris etc.

Cons- House prices are higher than a lot of the US. Houses adn flats are small, and tend to have a washing machine in the kitchen , which apparently baffles you guys.

Lack of wilderness. We have 10x the population density compared to the US, so there's no wilderness left in England. The countryside's beautiful- pretty farmland, often separated by hedges (often dating back 100s of years), or stone walls, but all the same, the countryside's mainly man made, aside from a few National Parks- and even some of them are denuded of trees, either 500 years ago when we cut everything down to build ships to go places, or even longer ago longer ago. OTOH, the countryside's also chock full of history, much of which is free- most castles and manor houses are open to the public, but you have to pay to enter. BUT- there's loads of ruined castles, which are often free, loads of ancient sites- standing stones, burial mounds and whatnot.

best of all, the countryside is cris-crossed with footpaths- often crossing private land- and they're all legal for anyone to walk along (Madonna got very uppity when she lived here that the proles were allowed to walk across her land). So if you like hiking, or just taking the dog for a walk, you'll love that. Most of the coast is publicly owned, too, so beaches are all public, and there's coastal paths (trails) along most of the coast, too- again. Youre never further than 100 miles from the sea in the UK.

Lots of single taps (faucets), rather than mixer taps, which annoys everyone, not just Yanks.

Petrol (gas) costs more, but public transport's more accruable too, though often not great in the countryside. But cars are smaller, so its not so bad. Most cars are stick tho. All the same, you can obvs drive to town, then take a train long distance. Rail network's good.

Almost everything's metric, except for pints of milk and beer, really, but you'll get used to it.

Its maybe not the best time to come. The country'll be fucked from covid for a while- unemployment's hard to predict, and the gov's throwing money at the green economy to counter that- but grief, depression, etc.. not a happy time... But that's going to apply most places, i guess.

No Mexican food. No Mexicans = no Mexican places.

It'll take a while to get used to the nuanced differences, and sometimes that'll make you feel homesick.
