Updated July 29, 2026. Quick answer: Frequently not — and when the answer is no it is usually not your advisor’s choice. The binding constraints sit with the custodian holding the assets and with local rules in the country you move to, and both are decided above your advisor’s head. The mistake is finding out after the move, when your options have narrowed to whatever your existing institutions will still do for a non-resident.
Who actually decides
| Constraint | Set by | Can your advisor waive it? |
|---|---|---|
| Whether the account can have a foreign address | The custodian | No |
| Whether new purchases are allowed from abroad | The custodian | No |
| Whether advice may be given to a resident of that country | That country’s regulator | No |
| Whether the firm wants the compliance burden | The firm | Sometimes, and this is the one worth asking about |
| Whether the relationship continues at all | All of the above | Rarely |
The sequence problem. Custodians commonly restrict accounts once the address of record becomes foreign, and the restriction is often to liquidate-or-hold rather than an outright closure. That is survivable if you knew it was coming and positioned first; it is expensive if it lands while you are mid-move and your only options are the ones your current institution still permits. The order of operations is the whole game, and it runs before the flight, not after.
The questions to ask, in writing, before you go
- Will the custodian permit a foreign address of record for the country I am moving to — and is the answer different for a brokerage account, a retirement account, and a cash account?
- If the address changes, can I still buy, or only hold and sell?
- Is the firm registered or otherwise permitted to advise a resident of that country?
- If not, does the relationship end, pause, or move to a different arm of the firm?
- What happens to automatic contributions, dividend reinvestment and rebalancing?
- Will you still produce the tax reporting I need, and in what form?
Why the incumbent pages do not answer this. The firms ranking for cross-border advice are the ones that do serve clients abroad, several with investable-asset minimums attached, so the page you land on is a pitch rather than an inventory of constraints. That is not dishonest — it is simply a different question from the one you asked, which is whether your current arrangement survives the move.
What changes on the tax side regardless of who advises you
Three things, and none of them depends on your advisor: whether your gains are even foreign-source turns on paying real tax abroad; the 3.8% surtax cannot be offset by foreign tax credits; and the exclusion that covers your salary does not touch your portfolio. Those are worth understanding before you choose who manages the money, not after.
