The dream of relocating abroad tends to arrive fully formed. You picture the apartment with the good light, the café around the corner where everyone knows your name, the slower pace of life that somehow also feels more alive. It’s a compelling image. The problem is that the image leaves out a lot.
The global expat population has reached its highest level in history, with more people choosing to live outside their home country than ever before. Whether for work, study, retirement, or lifestyle changes, millions of individuals are relocating across borders every year, with the number of people living outside their country of birth reaching around 300 to 304 million in mid-2024. That means millions of people are collectively learning the same hard lessons, often after it is far too late to prepare. Here are the eight things that rarely come up until you are already living them.
1. The Emotional Toll Is Far Greater Than Anyone Warned You
Over half of expats say the emotional stress of moving abroad was greater than expected. That is a striking figure, considering most people spend far more time researching apartment costs than they do thinking about psychological readiness. The move itself occupies you completely at first. Then, a few weeks in, the adrenaline fades.
Moving to a new country is often painted as a grand adventure, a story of exciting opportunities, new horizons, and personal growth. Yet there is another side to the story that is not talked about as often: the quiet moments of loneliness, the stress of adjusting to a completely new culture, and the ache of homesickness. Recognizing this in advance doesn’t make the feeling disappear, but it does prevent you from thinking something has gone terribly wrong when it arrives.
2. Making Real Friends Takes Much Longer Than You Expect
Global studies show that only about half of expats find it easy to make new friends abroad, which shows that significant effort is required to get out and build a new network. Most people assume that a new city means a fresh social start. In practice, it means starting from zero in a place where everyone else already has their routines, their circles, and their history.
Loneliness is not simply the absence of people. Many expats are surrounded by colleagues, classmates, or flatmates on a daily basis, yet still feel profoundly isolated – because loneliness is about the quality of connections, not the quantity. A common part of expat life is a regular stream of friends moving on and returning home, which makes it hard to build a strong network when everyone’s circumstances are temporary.
3. The Language Barrier Goes Deeper Than You Imagined
Roughly two fifths of expats struggle with language barriers, making it the most significant cultural challenge – with language difficulties affecting everything from ordering food and finding housing to building friendships. Survival-level communication is achievable within weeks. The kind of language fluency that lets you joke, negotiate a lease, or navigate a medical appointment comfortably – that takes years.
The language barrier tops the list in many surveys, with a significant share of respondents citing it as their primary hurdle. Many expatriates continue to face difficulties mastering the language even after several years in their new country, and while learning the language before relocating is highly recommended, the real-life environment significantly impacts the learning process. Progress is uneven and slower than any app will tell you.
4. Cultural Adaptation Is Harder the Second or Third Time Around
Despite many aspirations, most expatriates report significant challenges adapting to their host country’s culture. For nearly two thirds of respondents in a major survey, cultural adaptation is the most significant hurdle – and contrary to expectations, those who have relocated multiple times often find it increasingly difficult to adjust to cultural differences. Experience, it turns out, does not always build resilience here.
One thing many people do not fully understand before living abroad is that their expectations about work, community, and communication are products of their cultural upbringing. Many Western countries, for instance, have a culture of goal orientation, individualism, and transactional professional relationships, which clashes sharply with more community-oriented places. Those clashes rarely announce themselves – they just pile up, quietly, until you notice you are constantly frustrated.
5. Your Banking Life Becomes Surprisingly Complicated
Navigating banking as an expatriate involves several hurdles, primarily due to regulatory requirements and banks’ risk management policies. Some banks may close or restrict accounts for customers living abroad due to concerns about compliance with international regulations, including the Foreign Account Tax Compliance Act, and communicating with your bank about your expatriate status can sometimes prevent unexpected closures.
Banks abroad frequently hesitate to serve American clients due to FATCA-related reporting burdens, and expats often express frustration over being denied accounts or facing extensive documentation requirements. In 2024 and 2025, banking requirements for foreign clients became even stricter, with every document and the origin of funds scrutinized, sometimes requiring physical presence. Opening a simple current account can take weeks and multiple visits – something almost nobody thinks to plan for.
6. Your Tax Obligations Follow You Across Borders
One of the biggest misconceptions is that moving abroad ends U.S. tax filing obligations. As a U.S. citizen or green card holder, you must file U.S. tax returns regardless of where you live. The U.S. is one of only three countries in the world that taxes based on citizenship rather than residence. That is a structural reality that surprises a remarkable number of people mid-move.
Living in a foreign country does not exempt you from U.S. tax obligations – it only changes how they appear. For many American citizens abroad, the main difficulty is not paying taxes but understanding what has to be reported, where it goes, and exactly when it is due. Penalties for missed filings can be severe, and the paperwork complexity grows alongside your time abroad.
7. The Cost of Living Is Rarely as Affordable as the Blog Posts Suggested
Many countries can feel more affordable than the U.S., but living abroad is probably not as cheap as you think. Costs are rising around the world, especially housing prices, with house prices in the EU climbing by nearly 58 percent between 2010 and the first quarter of 2025. The affordable destination from a travel article written four years ago may already be a different financial reality on the ground.
Some people return home because the affordable country they moved to stopped being affordable. Gentrification is a global phenomenon, and popular expat destinations have seen prices surge, partly because of the influx of foreign income earners. Popular neighborhoods in cities like Lisbon, Mexico City, and Chiang Mai have all experienced this shift in recent years, sometimes dramatically so.
8. You May Never Fully Belong Anywhere Again – and That Takes Time to Process
Something nobody warns you about is that you might never fully belong anywhere again. When you are in your new country, you are the foreigner. When you visit home, you have changed so much that you do not quite fit there either. That in-between identity is genuinely disorienting, and it tends to arrive long after the honeymoon phase has worn off.
The distance from family and friends can be hard to bear, often accompanied by the guilt of having chosen to live abroad. Even after several years of living in another country, one’s sense of belonging and feeling at home can be pulled in two directions at once. Adopting a bicultural identity – integrating aspects of both home and host cultures – has been shown to improve mental health outcomes for expats over time. It is a process, not a resolution, and understanding that early makes a genuine difference.
None of this should be read as a case against moving abroad. Millions of people do it successfully every year and describe it as one of the better decisions of their lives. The point is simply that the full picture matters. The gap between expectation and reality is where most of the difficulty lives – and that gap shrinks considerably when you see it coming.
