At least 180,000 Americans left the United States in 2025.
But most of them probably picked their European city from YouTube videos, old travel guides, or simply the names they know and have seen in films. And a good number of them, from what I see, will be back within two years but tens of thousands of dollars lighter.
I’ve watched it from the local side for a decade and I’ve noticed a pattern. People choose the country on how it looks, then find the rest out too late: that the visa leads nowhere and is really a long holiday with a tax number, that the 401k withdrawal meant to fund the life arrives taxed as salary because nobody ran it past someone who knew the treaty, and that they have never experienced the place in February – which is the month that should decide whether you stay somewhere long-term.
What nobody tells you upfront is that the right choices depend entirely on who you are and what you’re looking for.
This guide is going to help you understand just that.
Why Europe, and why now
I left Italy about a decade ago, when Europe felt like a sinking ship and the wisdom in my circles was to go to Dubai for the tax and keep a Western passport in the drawer. I followed it, and over ten years I watched that wisdom not necessarily be proven wrong, but evolve.
Europe is a two-speed continent. It is a hard place to build a company: slow, protective, allergic to speed. But it has become one of the best places on earth to live if your income comes from somewhere else. What I tell Americans is to earn in dollars and spend in euros: a New York salary, a US pension, a portfolio in an American brokerage, all of it spent in a country where a full sit-down lunch costs fifteen euros and the hospital does not send you a bill.
But then why not a zero-tax island instead?
Because efficiency can be copied but depth cannot. You can rebuild Singapore’s efficiency anywhere with modern infrastructure and good internet. You cannot rebuild two thousand years of history that you get to see on your walk to the bakery or when you get your morning espresso.
There is also a window on this that most might not be aware of, and it is narrowing rather than opening. Portugal moved citizenship from five years to ten in May 2026, Spain closed its golden visa, Italy cut citizenship by descent to a parent or grandparent born in Italy, and the nomad visas that were easy in 2022 now want more income and a consulate appointment. Meanwhile a record 80,000 first residence permits went to US citizens in the EU last year, and in Portugal and Italy more than half of those Americans are over fifty.
So the opportunity is real but the window is progressively closing. But knowing this doesn’t help you in deciding where to go.
Which of these six profiles are you?
“Which country is best for Americans” is the wrong question to start with.
A New Yorker and a Californian likely want different things, and so do a retiree, someone who has just sold a company, a remote worker on a W-2 and a family with children in school. The country that suits one of them will fail another, so everything here is tagged for one of the six below.
There are also two schools of thought, and which one you belong to will narrow down your list immediately. One goes for the second city, Porto over Lisbon, Valencia over Barcelona, and gets half the price and more local life for it. I am mostly in that school and this guide is built on it. The other goes for the famous place because it was always the dream.
The retiree. Sixty or older, living on a pension and Social Security. Healthcare should primarily choose your country, not tax. At forty-five you ignore the hospital question, but at seventy you can’t.
The early retiree. Forty-five to sixty, a portfolio behind you and no Medicare for a decade, so two questions narrow the list: does the country’s visa accept a portfolio instead of a pension, and will an insurer there still take you at sixty-eight.
The descent citizen. An Italian grandmother or an Irish grandfather makes most of the visa talk in this guide irrelevant to you. The cheapest way into Europe for you may already be decided.
The remote earner. You kept the American income, W-2 or 1099 or your own company, which is the best decision in this guide and you might have already made it before reading this. The only question left is whether the visa you are looking at leads to residence or simply runs out.
The family. The school chooses your country before the visa or the tax does, and the age of your child on the day you land decides the rest: under ten the local school is a gift, and over thirteen the international one is the biggest line in your budget.
The career mover. You get the shortest verdicts in this guide, because for most Americans careers stay in the United States: a $120,000 role in Austin is a €65,000 role in Berlin, so the job has to be worth more than the money. Sometimes it is.
What actually decides whether the move works
The tax treaty. The United States taxes you forever and wherever, so the treaty matters more than the rent price: France protects your Social Security, your 401k and in practice your Roth, while Spain taxes a 401k drawdown as salary at up to 47%.
Where your money comes from. Earn in dollars and spend in euros, because the moves that fail are the ones where someone traded an American salary for a European one.
A visa that keeps renewing. For example, Croatia gives you eighteen months and then nothing, Spain gives you three years and a path to permanent residence – but on the brochure the two look the same.
The language. English gets you through getting a visa or buying a coffee, but not day-to-day life. The countries sold to you as “everyone speaks English” are often the loneliest, because the locals switch for you and you never really assimilate.
The bill that follows you home. Medicare stops at the border and your US tax obligations never do, and the institutions that shut you out for being American are mostly American ones, your own bank and your own brokerage.
A community that is still there in February. Enough foreigners around that you are not completely isolated, and enough of them staying that your friends are not all gone by spring. Next to the others this one might sound soft, but I’ve seen it be highly influential in making decisions.
How to use this guide
Every place is laid out the same way. Best for names the profiles it suits, so if none of them is you, skip the entry. The practical line gives you the rent, the airport and how easily you get home, followed by the case for the place. The catch is everything else that you should know that could be problematic.
