The letter is polite. It thanks you for your years as a valued customer. It informs you that, following a review of your account, the firm is no longer able to maintain brokerage services for residents of your country. You have sixty days to transfer your assets to another institution. If you do not, your positions will be liquidated, and a check will be mailed to your address on file.
Your address on file is the problem. It’s in Lisbon now, or Valencia, or Milan — which is why the letter exists. And the check they’re threatening to mail will take three weeks to reach you, be denominated in dollars, and be nearly impossible to deposit into the local bank account you also don’t have yet, for reasons this piece will get to.
By one industry count, roughly 340,000 accounts belonging to Americans abroad were closed in 2025 alone. Not frozen for fraud. Not flagged for crime. Closed because the account holder committed the act of living somewhere else and then told the truth about it on an address-change form.
Most people learn this system exists by receiving the letter. The entire point of this piece is that you learn it now instead.
Why the machine does this
The instinct is to take it personally — to hear “we can no longer serve you” as a bank being difficult, or cowardly, or anti-expat. The instinct is wrong, and getting the diagnosis wrong leads to the wrong response. Your bank is not making a decision about you. It is responding to regulatory geometry, and the geometry is worth understanding because it predicts exactly which institutions will keep you and which will fire you.
Three forces converge on your account the day your address changes.
The first is securities registration. A US broker-dealer is licensed to serve residents of US jurisdictions. When you become a resident of Portugal, your broker is now servicing a client in a jurisdiction where it holds no license, under a regulator it has no relationship with, subject to consumer-protection and marketing rules it has never read. For a firm with millions of clients, building compliance infrastructure in dozens of countries to retain a few thousand expats is a cost with no offsetting revenue. The rational move is to fire the client. So they do.
The second is European product regulation. If you land in the EU, MiFID II and the PRIIPs regime require that funds sold to EU residents carry a specific disclosure document. Almost no US-domiciled ETF or mutual fund produces one, because the US market is the whole business and Brussels is a rounding error. The result: many firms conclude they cannot legally sell you a US ETF anymore — and some conclude they’d rather not have EU-resident clients at all. This is why the same brokerage that shrugs at a client in Mexico City sends termination letters to clients in Paris. The geometry is jurisdictional, not personal.
The third is the compliance cost curve. Anti-money-laundering rules, know-your-customer refreshes, sanctions screening — all of it gets more expensive when the client is abroad, and the expense is per-client while the revenue is per-dollar. A $200,000 account in Omaha is profitable. The same account in Osaka is a compliance file with a small brokerage account attached.
None of these forces care how long you’ve been a customer. Tenure is not a variable in the equation.
How they find out
The trigger is almost always self-reported: you update your address, because you are an honest person doing the responsible thing. But the address form is only the front door. Firms also flag accounts on IP geolocation when your logins consistently originate abroad, on customer-service calls from foreign numbers, and on tax-residency data that propagates from other parts of the institution. The compliance systems were built to catch money launderers. You are not one, but you present the same data signature: a US account operated persistently from foreign soil.
And here is the asymmetry that surprises people: the discovery is not an event, it’s an eventuality. You are one address form, one W-9 refresh, one KYC cycle away from the letter, indefinitely. The question is never whether the institution learns where you live. The question is whether you have arranged your affairs before it does.
What the letter actually costs
Read the sixty-day clause again, because it’s carrying more weight than it appears to.
If you don’t move the assets in time, the firm liquidates them. Liquidation is a sale, and a sale is a realization event. Every appreciated position in a taxable account — the index funds you’ve held for fifteen years, the employer stock with a cost basis from another decade — gets sold in a single tax year, at a moment chosen by a compliance department, generating capital gains you did not plan for, in the first year of a cross-border tax life you have not yet figured out. Depending on your new country’s rules and the treaty, you may owe tax on those gains in two jurisdictions with imperfect crediting between them. A forced sale in transition year is close to the most expensive possible moment for gains to land.
Even the orderly path — transferring out — has teeth. Mutual fund shares frequently cannot move between brokerages at all; they have to be converted or sold first, and conversion is possible cleanly at some firms and taxable at others. Fractional shares don’t transfer; they’re liquidated. Cost-basis records get mangled in transit often enough that the standard practice is to pull a full basis statement before the transfer, because reconstructing it afterward, from abroad, is its own small nightmare.
Retirement accounts add a quieter problem: an IRA needs a US custodian, and custodians can refuse foreign-resident clients too. Nobody loses the IRA’s tax status by moving — but plenty of people discover their custodian will no longer let them trade inside it, or accept a rollover, and the number of custodians who affirmatively welcome foreign-resident IRA holders is small and shrinking.
So the naive path — move, update the address, deal with whatever happens — has a defined failure mode with a five-to-six-figure price tag on a large portfolio. Which is why nearly everyone who thinks about this for ten minutes lands on the same workaround.
The workaround that makes it worse
Keep a US address. A parent’s house, a sibling’s condo, a commercial mailbox service. Don’t tell the bank anything. Log in through a VPN. Problem solved.
I understand the appeal, and I’m telling you it’s the worst of the available options — not because it fails immediately, but because of how it fails.
First, it converts an administrative inconvenience into a misrepresentation. Your account agreement requires accurate residence information; some account features and insurance coverages hinge on it. When the firm eventually detects the pattern — and mailbox-service addresses are on lists, and login geography is logged — you are no longer a valued customer in the wrong country. You are a client who concealed material information, and the closure that follows is immediate rather than orderly. The sixty-day letter was the good outcome. This version is a frozen account and a liquidation you learn about afterward.
Second — and this is the part almost nobody prices — the fake US address is a tax document. It appears on your 1099s. It tells your former state that you still live there. If you left California or New York while “residing” at your brother’s place in Sacramento for banking purposes, you have manufactured the single best piece of evidence the residency auditor could ask for. You’ve read what I’ve written about domicile severance; the address workaround un-severs it, in writing, every January. The banking problem and the state-tax problem are the same problem wearing different hats, and this workaround solves neither while feeding both.
Third, it postpones the real work without shrinking it. Every account anchored to the fictional address still has to be restructured eventually — from abroad, under time pressure, after a discovery event, which is the hardest possible configuration.
So: the honest path triggers the machine, and the dishonest path triggers it worse, later, with a residency audit attached. Both failure modes share a root cause — the accounts were structured for a US resident, and the residency changed before the structure did.
Which points at the actual answer. The institutions that will keep you exist. The account architecture that survives a foreign address exists. The reporting obligations that come with the foreign accounts are manageable if you know the thresholds before you cross them. But all of it shares one property: it works in exactly one direction, and the direction is before.
