A cheap portfolio is easy to describe. Opening the account that will hold it is the part people skip. If you live in one country, earn in another, and might move again, a domestic wrapper and a high-street broker that only accepts local residents assume one tax residence. This piece is for English-speaking readers who need a brokerage account that will still open and report after a visa change. It is not a “best broker” ranking, and it is not tax advice.
Other product names below are illustrative. Where a Wise link appears, Bankrolled may earn a commission if you sign up through it. Read the broker’s own help pages, the tariff that applies to your entity, and the register in the country that actually taxes you.

What to hold once the account exists is covered in A low-cost portfolio when you are not in one tax jurisdiction. This article is the account layer: who will take you, which legal entity you sit with, and what that implies for reporting.
This is general information, not personalised advice.
Why a local high-street broker often is not the tool
A broker licensed only in the country you currently live in can be simple until you leave. Many retail platforms restrict new accounts by residence or freeze funding when your address changes. If your working life already spans more than one country, you want a firm that opens for non-residents, has more than one regulated affiliate, will collect tax-residency information, and publishes a commission and FX schedule you can read before you click.
Interactive Brokers (IBKR) is the example used here because it is a common option among English-speaking expats and because its tax-residency, pricing, and client-protection pages are public. That is not an endorsement, and it is not a comparison table. Eligibility, product access, and the affiliate that carries your account still depend on where you live and whether you are a US person. Check the application, not a blog.
The entity is the account
IBKR is a group, not a single licence. Interactive Brokers LLC in the United States, Interactive Brokers Ireland Limited, Interactive Brokers Singapore Pte. Ltd., Interactive Brokers Australia Pty Ltd, and the other affiliates named on IBKR’s disclaimers page are different legal persons. The application assigns you to one of them based on residence. Client agreements, investor-protection schemes, and sometimes the commission schedule follow that entity.
Interactive Brokers LLC states that client securities accounts are protected by the US Securities Investor Protection Corporation (SIPC) up to a published maximum, with a cash sublimit, and that this is protection against broker-dealer failure, not against a fall in market value. Interactive Brokers Ireland Limited is described on IBKR’s disclaimers page as regulated by the Central Bank of Ireland and a member of the Irish Investor Compensation Scheme. Interactive Brokers Singapore Pte. Ltd. is licensed by the Monetary Authority of Singapore. Those are not interchangeable wrappers. A Singapore brokerage holding is not a bank deposit, and it is not covered by the Singapore Deposit Insurance Scheme, which SDIC’s FAQs limit to insured SGD deposits with scheme-member banks and finance companies.
Name the entity on a card in your notes the day the account opens. If you move country, ask which affiliate will carry you next. Do not assume SIPC, an Irish scheme, or MAS segregation travels because the app logo stayed the same.
Tax residency is a form, not a strategy
IBKR’s tax-residency help is blunt: the firm must withhold, remit, and report, and it needs your primary tax residency to know where to send information and which withholding rate to apply. US citizens and green-card holders are US tax residents on that page regardless of where they live. Residents of other countries are treated as foreign persons unless they are also US persons. Non-US individuals complete a Form W-8; IBKR’s non-US application notes say a valid W-8 must be on file and renewed, and that an expired form can mean default US withholding.
That paperwork is reporting infrastructure. The OECD Common Reporting Standard is why a broker in Ireland or Singapore will ask where you are resident and then report account data for automatic exchange. FATCA is why a US person faces a different set of forms. Neither is a reason to avoid a brokerage account, and neither is a tax-planning tool. Fill in the residence you actually have. When it changes, tell the broker.
US persons and everyone else are not the same customer. The Grow cornerstone sets out why a non-US fund can be a PFIC for a US person. Choose a broker that will accept your status and issue the forms that status requires.
Costs you can read before you fund
Three costs matter. Trading costs: commissions, FX conversion, and exchange or regulatory pass-throughs. IBKR publishes commission schedules. Those pages change. This article quotes no rate. Open the schedule that matches your entity on the day you care. Funding: how you get money in from the payment account in Moving money across borders without a UK bank, and how long a withdrawal takes. A brokerage account is a poor operating account. The wrong fund domicile is not fixed by a cheap commission.
A default that does not need a domestic wrapper
Open one brokerage account at a firm that will still take your residence next year. Complete the tax forms as they are. Fund it from the multi-currency payment account you already use to get paid, in a currency the broker accepts. Hold the portfolio described in the Grow cornerstone — a domicile that matches your US-person status, small enough to explain after a visa change. Keep spending cash out of the brokerage account.
If a country where you live offers a local pension or savings wrapper, treat it as optional and local. It does not replace the brokerage account, and it does not travel when you leave.
What this article is not
It is not a league table. It does not tell you Interactive Brokers is the cheapest, the safest, or the right firm for your facts. It does not apply FSCS to ETFs. It does not invent a commission, a margin rate, or an expected return. If a figure is not on IBKR’s own page, SIPC, SDIC, or a regulator page dated 2024–2026, it is not here.
