Expats make friends faster than almost anyone, and lose track of them just as fast.
Research on expat social patterns describes a real “expat bubble” effect: shared circumstance bonds people faster than geography does. It’s also, quietly, why those friendships are some of the easiest to lose.

Move to a new country for work, and something strange tends to happen within the first few weeks: you end up with friends faster than you probably have anywhere else in your adult life. It isn’t a coincidence, and it isn’t really about you either.
It’s a documented pattern with a name, and, less talked about, a real tradeoff attached to it.
The expat bubble, explained
Anyone who's moved abroad for work has probably noticed it without naming it: the friends who show up fastest tend to be other expats, not locals. There's a name for this in writing on expat life, the expat bubble, and it isn't just a coincidence of convenience.
Shared circumstance turns out to bond people faster than most other things do. Two people navigating the same visa paperwork, the same unfamiliar grocery store, the same specific loneliness of a Tuesday with nothing on the calendar, have an unusual amount in common on day one, even if they'd have nothing to talk about back in their home countries.
Why it happens so fast
Part of it is simple math: expats are, almost by definition, actively looking to build a social circle from nothing, which makes them more receptive to a stranger's overture than most people are in their settled, established home lives. Approaching someone new carries less social risk when neither of you has an existing circle to protect.
Part of it is also that shared disorientation is a genuinely fast way to skip small talk. "How long have you been here" and "what do you miss most" get to something real a lot faster than the usual getting-to-know-you script, because you're both, quite literally, in the same unfamiliar place at the same time.
The tradeoff nobody mentions
The same thing that makes expat friendships form quickly also makes them unusually fragile: everyone in the bubble is there because they moved once, which means most of them are statistically likely to move again. Corporate assignments abroad commonly run somewhere between one and five years, often closer to two or three, and international careers frequently mean repeated relocations, not one.
That's a different failure mode than the slow fade a hometown friendship goes through. A friendship that formed over eighteen months in the same city can end with a single flight, not a gradual drift, and the sudden ending can catch people off guard precisely because the friendship felt so solid while it lasted.
Locals matter too, not just other expats
It's worth being honest about a second finding alongside the bubble effect: expats who make an effort to build relationships with host-country nationals, not just other expats, tend to report higher satisfaction and less homesickness than those who stay entirely inside the bubble. The bubble is real and it's genuinely useful, but it isn't the whole answer on its own.
The practical takeaway isn't to avoid other expats in favor of locals, or the reverse. It's that a full social picture abroad usually ends up with both: the fast, easy camaraderie of people going through the same thing you are, and the slower, deeper roots that come from actually building a life somewhere, not just passing through it alongside other people who are also passing through.
What actually holds on
None of this is an argument against expat friendships, fast and eventually fragile is still real while it lasts, and worth having. It's an argument for capturing them while they're happening instead of assuming a group chat will hold the memory for you. A group chat tends to go quiet the moment one person moves, not because anyone meant to let it fade, just because the shared context that made it easy disappears with the move.
A signed page does something a group chat doesn't: it fixes a specific memory in place with both of your names on it, before the bubble that made it possible moves apart. That's true whether it's someone met three months into a new job or a friend from home twelve time zones away, and it's the actual mechanic behind how yeerbook works for people living abroad.
What actually helps, given how this works
- 1
Treat the shared-circumstance small talk as real, not filler
"How long have you been here" and "what do you miss most" aren't throwaway questions abroad, they're doing the actual work of finding common ground fast. Answer them honestly instead of deflecting to small talk you'd use at home.

Make the first move rather than waiting for the bubble to form on its own
A lot of the bubble's early friendships trace back to someone deciding to approach a stranger, not to proximity doing the work by itself. The social risk is genuinely lower here, since neither of you has an established circle to protect, so it's a good place to practice being the one who reaches out first.

Deliberately pursue at least one host-country friendship too
Not instead of the expat bubble, alongside it. The satisfaction and homesickness research points the same direction either way: both circles matter, and the bubble alone tends to be an incomplete answer.

Capture a friendship while it's actually happening
Don't wait for a going-away party to say what a friendship meant. A private link lets a friend sign a specific memory directly, tagged with both your names, while you're still in it, not after the context that made it possible has already moved apart.
For more on how yeerbook holds both circles, the friends you’re making here and the people back home, in the same book, see yeerbook for life abroad.
Frequently asked questions
Why is it so much easier to make friends as an expat?
Shared circumstance. Two people navigating the same unfamiliar systems, the same homesickness, the same early loneliness, have an unusual amount in common immediately, even if they'd have little to talk about back home. This pattern is often called the "expat bubble": expats disproportionately befriend other expats over locals, at least at first.
Why do expat friendships often fade after someone moves?
Because the bubble that made the friendship form quickly is made up of other people who are also likely to move. Corporate assignments abroad commonly run one to five years, so the same transience that made a friendship easy to start also makes it end abruptly, with a flight, rather than fading slowly the way a hometown friendship usually does.
Should I try to make friends with locals or other expats?
Both, ideally. Expat friendships form fast and offer real camaraderie, but research also links relationships with host-country nationals to higher satisfaction and less homesickness. Neither circle replaces the other.
How can I actually make friends faster as an expat?
Lean into the questions that feel too direct at home, "how long have you been here" genuinely works abroad. Make the first move instead of waiting for it to happen on its own, since the social risk is lower when neither of you has an established circle yet. And pursue a host-country friendship alongside the expat ones, not instead of them, since relying on the bubble alone tends to leave people less settled, not more.
How does a yeerbook help with friendships that might not last long term?
It doesn't try to prevent a friendship from ending when someone moves, that's not really something an app can fix. It captures the friendship while it's happening: a private link lets a friend sign a specific memory directly, so there's a real, dated record of it, rather than relying on a group chat to remember something it was never built to hold onto.
