The letter nobody warns you about
You update your address with your US brokerage after a move to Paris, Lisbon or Milan. A few weeks later a notice arrives. Your account is being restricted to closing transactions only. Or you can no longer buy mutual funds. Or the account is being closed altogether, and you have sixty or ninety days to move the assets somewhere else.
This surprises most people, because nothing about their situation has changed except a mailing address. The portfolio is the same. The tax obligations to the United States are the same, since American citizens are taxed on worldwide income regardless of where they live. Yet the account that held everything together for twenty years is suddenly a problem.
Policies differ between firms and change without much notice. Some brokerages maintain full service for clients abroad, some restrict trading, some exit the relationship entirely, and several treat each country differently. Do not assume your firm behaves like your neighbour's.
Why it happens, and why it is not about you
The decision is almost never about your balance or your conduct. It is about where advice and solicitation are considered to take place.
When a client resides in another country, the firm serving that client may be treated as doing business in that country. That can trigger local licensing requirements, local supervision, and local investor protection rules. For a large US brokerage with a domestic client base, obtaining and maintaining permissions across a dozen European jurisdictions to serve a handful of relocated clients is rarely worth the cost. Restricting or exiting those relationships is the cheaper answer.
Layered on top of that are anti money laundering obligations, differing suitability standards, and rules on how investment products may be marketed across borders. None of it is personal. All of it lands on you.
The four outcomes you may face
Full service retained. Some firms continue to serve clients in certain countries without change. This is the best case and it is worth confirming in writing before you move.
Restricted to liquidation only. You keep the account but can only sell. Over time this forces your allocation to drift, and it removes your ability to rebalance or reinvest dividends.
Product level restrictions. The account stays open but certain instruments become unavailable. Mutual funds are the common casualty, which matters if your portfolio was built around them.
Closure. The account is terminated and you must transfer or liquidate within a set window. Forced liquidation on a deadline is how unnecessary capital gains get realised.
Why a European bank is usually not the fallback
The instinct is to open an account with a bank in your new country. For US citizens this often runs into a second wall.
Under the Foreign Account Tax Compliance Act, foreign financial institutions must identify and report accounts held by US persons to the US authorities. Many European banks decided the compliance burden was not worth the revenue and simply stopped accepting American clients, or accept them for basic banking while excluding them from investment products.
There is a second issue that catches people who do find an accommodating bank. Most European investment funds are treated as passive foreign investment companies under US tax rules. The reporting is onerous and the tax treatment can be punitive. An American who solves the account problem by buying local European funds can create a worse problem than the one they started with. This is an area where qualified US tax counsel matters, and where generic advice is dangerous.
The structure that does work
The combination that resolves this is specific. You need an adviser registered with the US Securities and Exchange Commission, so that serving a US person remains within a recognised regulatory framework, and you need custody arrangements in Europe, so that the assets sit where you live and where local banking relationships can be built on top of them.
That combination is uncommon. Most SEC registered advisers are domestic US firms with no European presence. Most European wealth managers are not SEC registered and therefore avoid US persons. The clients who fall between the two are exactly the people this article is about.
Where that structure exists, several things become possible again. Your portfolio can be managed rather than frozen. You can access investment products through European custodians. And crucially, an investment portfolio held under a regulated adviser can serve as the basis for a property financing conversation with European banks, which is often the next problem an American faces after the account problem is solved.
What to do before you move
Ask your current brokerage, in writing, what happens to your account if you become resident in the specific country you are moving to. Verbal reassurance from a call centre is not a policy.
Establish where the assets would go if the answer is unfavourable, before the sixty day clock starts. Decisions made under a deadline are worse than decisions made with time.
Understand the tax consequence of any forced sale. A liquidation you did not choose is still a taxable event.
Speak to a US tax professional about the treatment of non US funds before you buy anything locally.
If it has already happened
You have more room than the letter suggests. A transfer of positions in kind, where the securities move rather than being sold, avoids realising gains you did not intend to realise. Whether that is available depends on the receiving institution and the instruments held, which is the first thing to establish.
Extensions are sometimes granted when a receiving account is demonstrably being opened. It is worth asking.
Where Amberlake Partners fits
Amberlake Partners is the first wealth manager based in Monaco to be registered with the US Securities and Exchange Commission. The firm is authorised and regulated by the Commission de Contrôle des Activités Financières in Monaco, and its SEC registration can be verified directly on the regulator's public register.
That registration is what allows the firm to advise US persons resident in Europe, using custody arrangements across Monaco, Geneva, Luxembourg, Madrid, New York, Miami, Dubai and Singapore. Amberlake is independent and operates on open architecture, with no in house products to place.
If your US brokerage has restricted or closed your account, or you are planning a move and want to know what you are walking into, a conversation costs nothing and takes twenty minutes.

Common questions
Will my US brokerage account be closed if I move abroad?
It depends entirely on the firm, and policies change without notice. Some maintain full service, some restrict the account to sales only, some remove access to mutual funds, and some close it. Ask your brokerage in writing about your specific destination country before you move rather than after.
Why do US brokerages restrict accounts once a client moves abroad?
The reason is regulatory rather than personal. Serving a client resident in another country can amount to doing business there, which brings licensing and supervision requirements a domestic US firm has little reason to take on for a small number of relocated clients.
Can I just keep using a relative's US address?
We would advise against it. It misstates your circumstances to a regulated institution, it tends to be discovered through login patterns and correspondence, and the usual outcome is a forced closure at a moment you did not choose. It also does nothing about the underlying reporting position.
Can an SEC registered adviser manage my assets while I live in Europe?
Yes. That registration is what allows a firm to advise American citizens and green card holders resident outside the United States, with custody held at a bank rather than by the adviser. It is the structure most commonly used when a domestic US relationship becomes unworkable after a move.
