Investing in U.S. stocks can be attractive to international investors because the United States has one of the world’s largest and most liquid financial markets. But if you live outside the United States, choosing a brokerage account can be more complicated than simply downloading an investing app and opening an account.

The best brokerage account for a nonresident alien in the USA should offer access to U.S. stocks and ETFs, accept applicants who live outside the United States, provide appropriate tax documentation, offer reasonable trading costs, and make it relatively easy to deposit and withdraw funds internationally.

In 2026, Interactive Brokers and Charles Schwab’s international brokerage offering stand out as two of the most important options for international investors. However, the right choice depends heavily on your country of residence, investment goals, account size, currencies, and tax situation.

What Is a Nonresident Alien?

For U.S. tax purposes, a nonresident alien (NRA) is generally a person who is not a U.S. citizen or U.S. national and does not qualify as a U.S. resident for tax purposes under the applicable rules.

Being a nonresident alien does not automatically prevent you from investing in U.S. securities.

However, the distinction between a U.S. resident alien and a nonresident alien is extremely important because tax reporting and withholding can be different.

For example, the IRS states that nonresident aliens are generally subject to U.S. tax on U.S.-source income. Certain passive income, including dividends, can generally be subject to a 30% withholding rate unless a tax treaty provides for a lower rate.

Your tax residency should therefore be accurately reported when opening a brokerage account.

Best Brokerage Accounts for Nonresident Aliens in 2026

Here are some of the strongest brokerage options to investigate if you live outside the United States.

Brokerage	Best For	International Investors	U.S. Stocks/ETFs	Key Advantage
Interactive Brokers	Overall international investing	Yes, subject to country eligibility	Yes	Global access and multiple currencies
Charles Schwab International	Long-term U.S. investing	Yes, in qualifying countries	Yes	Strong U.S. market access
Firstrade	Low-cost investing	Availability varies	Yes	Simple investment platform
Other local/international brokers	Country-specific needs	Depends on jurisdiction	Often	Local support and regulations

The most important point is that not every broker accepts applicants from every country. Always check your country of residence before starting an application.

1. Interactive Brokers — Best Overall for Many International Investors

Interactive Brokers is one of the most attractive choices for investors who live outside the United States.

The company explicitly states that it accepts clients from citizens or residents of many countries, subject to restrictions involving sanctioned or higher-risk jurisdictions. Its current available-country list includes numerous countries across Africa, Asia, Europe, and other regions.

This makes Interactive Brokers particularly interesting for someone searching for a U.S. brokerage account for non-U.S. residents.

Why Interactive Brokers stands out

Interactive Brokers provides access to a broad range of markets and securities. Its IBKR Pro offering provides access to more than 170 markets across 40 countries, while IBKR Lite provides commission-free trading for eligible U.S. stocks and ETFs.

International investors may also benefit from its multi-currency capabilities, which can be useful if your income and savings are held outside the United States.

Who should consider Interactive Brokers?

Interactive Brokers may be particularly suitable for:

Non-U.S. residents who want broad international market access
Investors who trade U.S. stocks and ETFs regularly
Investors who hold multiple currencies
Experienced investors
Investors who want access to markets beyond the United States

One important limitation is that not every account type is available to nonresident aliens. For example, Interactive Brokers states that its IRA accounts are available only to U.S. citizens living anywhere and U.S. resident aliens.

For many nonresident aliens, a standard taxable brokerage account is therefore the more relevant option.

2. Charles Schwab International — Best for U.S. Market Investing

Charles Schwab is another major name worth considering.

Schwab offers an international brokerage service specifically designed for people who live outside the United States and want to invest in U.S. markets.

Schwab says investors living outside the U.S. can open an international account if they reside in a qualifying country. Applicants generally need documents such as a valid passport or government identification and proof of residence.

Why choose Charles Schwab International?

The Schwab One International account provides access to U.S. markets and lists $0 online commissions for listed U.S. equities, although certain securities, transactions and services can carry fees.

This can make Schwab appealing to investors who primarily want to buy and hold U.S. stocks and ETFs rather than trade securities across dozens of international markets.

Who is Schwab best for?

Schwab International may be a strong choice for:

Long-term investors
Investors primarily interested in U.S. stocks
Investors looking for an established U.S. brokerage
International investors who prefer a straightforward U.S.-market-focused account

The major consideration is country availability. Schwab does not necessarily offer the same international account options to residents of every country.

3. Firstrade — Another Option to Investigate

Firstrade is another U.S. brokerage that may be considered by international investors, although availability and account requirements can depend on the applicant’s country.

Its appeal is primarily centered around low-cost investing and access to U.S. securities.

However, nonresident investors should confirm directly with the brokerage whether new applications are currently accepted from their specific country of residence before relying on it as their primary option.

For international investors, country eligibility should always come before comparing small differences in commissions.

What Should Nonresident Aliens Look for in a Brokerage Account?

Choosing the cheapest broker is not necessarily the best strategy.

International investors should evaluate several factors.

1. Country Eligibility

This should be the first question.

A broker can be excellent for U.S. residents but completely unavailable to someone living abroad.

Interactive Brokers, for example, maintains a country eligibility list that includes many countries but excludes certain jurisdictions.

Always check your country before completing an application.

2. U.S. Stock and ETF Access

If your goal is to invest in companies such as Apple, Microsoft, Amazon, Nvidia or broad-market ETFs, make sure the broker provides access to the securities you want.

A good international brokerage should make it reasonably easy to purchase and hold U.S.-listed securities.

3. Currency Support

Currency conversion can become a significant cost for international investors.

If you earn money in euros, pounds, Canadian dollars, Nigerian naira or another currency, consider:

FX conversion costs
Supported deposit currencies
Withdrawal currencies
Bank transfer fees
Currency conversion spreads

A broker with strong multi-currency functionality can be particularly useful for investors who regularly move money between currencies.

4. Fees and Commissions

Don’t look only at the advertised stock commission.

International investors should examine the complete fee structure, including:

Stock commissions
Options commissions
Currency conversion costs
Wire transfer fees
Withdrawal fees
Market data fees
Inactivity fees, if applicable
Broker-assisted trading fees

A brokerage offering $0 stock trades can still be expensive if its other costs are high.

5. Tax Documentation

This is one of the most important differences between investing as a U.S. person and investing as a foreign investor.

Non-U.S. investors generally need to provide appropriate tax documentation to establish their foreign status.

For example, the IRS says Form W-8BEN is used by eligible foreign individuals to establish that they are not U.S. persons and, when applicable, claim a reduced withholding rate under an income-tax treaty.

Interactive Brokers likewise states that non-U.S. persons must complete an applicable W-8 form to certify their tax residency and establish whether they qualify for reduced withholding.

How Are U.S. Stocks Taxed for Nonresident Aliens?

Taxes are one of the biggest reasons to understand your brokerage account before investing.

The U.S. tax treatment of investment income for nonresident aliens can differ significantly from that of U.S. citizens and resident aliens.

Dividends

U.S.-source dividends paid to a nonresident alien are generally subject to 30% U.S. withholding, unless a lower rate applies under an applicable tax treaty.

For example, if a U.S. company pays you $1,000 in dividends and a 30% withholding rate applies, $300 could be withheld for U.S. tax purposes, leaving $700 before considering any other applicable taxes or charges.

The actual rate can be lower when a tax treaty between the United States and your country provides a reduced rate and you properly qualify for the treaty benefit.

Capital Gains

Capital gains can be treated differently.

The IRS generally states that capital gains of a nonresident alien who is present in the United States for fewer than 183 days during the tax year are generally not subject to U.S. tax, subject to important exceptions.

If a nonresident alien is present in the United States for 183 days or more during the tax year, certain U.S.-source capital gains can instead be subject to a 30% rate or a lower treaty rate.

This is one reason international investors should not assume that the tax treatment of U.S. investments is identical for everyone.

Your country of residence may also impose its own tax on investment income and gains.

Do Nonresident Aliens Need an SSN to Open a U.S. Brokerage Account?

Not necessarily.

The documentation required depends on the brokerage, your country of residence, your tax status and the type of account you are opening.

A brokerage may request information such as:

Passport or government-issued identification
Residential address
Country of tax residence
Foreign tax identification number
Form W-8BEN
Employment information
Source of funds
Banking information

For example, Schwab’s international application information says applicants may need a valid passport or government ID and proof of residence.

Interactive Brokers also describes identity and address verification requirements for applicants.

Never provide false information simply because a brokerage application asks for a U.S. tax number.

Can You Buy U.S. Stocks While Living Outside the USA?

Yes, in many cases.

You do not necessarily need to live in the United States to invest in U.S.-listed stocks.

The key issue is whether the brokerage accepts clients who reside in your particular country.

For example, Interactive Brokers currently lists a large number of eligible countries and territories for account opening.

Charles Schwab also offers international brokerage accounts to investors residing in qualifying countries.

Therefore, an investor living abroad should think about the process as:

Country eligibility → account eligibility → tax documentation → funding → investing

rather than simply looking for a U.S. investing app.

Best Brokerage Account for Nonresident Aliens: Interactive Brokers vs. Schwab

Feature	Interactive Brokers	Charles Schwab International
International applicants	Yes, subject to eligibility	Yes, qualifying countries
U.S. stocks	Yes	Yes
U.S. ETFs	Yes	Yes
International markets	Excellent	More U.S.-focused
Multi-currency capabilities	Strong	Available depending on account/service
Best for	Active/global investors	U.S.-focused long-term investors
Tax documentation	W-8 process for non-U.S. persons	International account documentation
Country restrictions	Yes	Yes

Which one is better?

Choose Interactive Brokers if you want a highly international platform, multiple markets, multiple currencies and extensive investment flexibility.

Consider Charles Schwab International if your primary objective is investing in U.S. stocks and you live in a country where Schwab offers its international brokerage account.

Neither is automatically the best for everyone.

How to Open a U.S. Brokerage Account as a Nonresident Alien

The application process generally looks like this:

Step 1: Confirm your country is supported

Go to the broker’s official website and check whether residents of your country can apply.

Step 2: Choose the appropriate account

For many nonresident investors, this will be an individual taxable brokerage account.

Do not assume that retirement accounts available to U.S. residents will also be available to you.

Step 3: Provide identity information

You may need a passport or other government-issued identification.

Step 4: Provide proof of residence

A brokerage may request documentation such as a recent utility bill or bank statement.

Schwab specifically identifies proof of residence as part of its international account-opening requirements.

Step 5: Complete your tax information

Non-U.S. persons generally need to establish their foreign status and tax residency.

Form W-8BEN is particularly important for eligible foreign individuals.

Step 6: Fund the account

Once approved, follow the brokerage’s instructions for funding your account.

International bank transfers may involve fees and currency conversion costs.

Step 7: Start investing

After funds arrive, you can purchase eligible U.S. securities according to the account’s permissions and the laws applicable to you.

What About Robinhood, Webull and Fidelity?

Many investors searching for the best U.S. brokerage account for foreigners immediately think about popular U.S. investing apps such as Robinhood, Webull or Fidelity.

The important issue is that being a popular U.S. brokerage does not automatically mean that it accepts nonresident aliens living abroad.

For example, some products are specifically designed for U.S. residents or U.S. tax residents.

Therefore, international investors should verify residency eligibility, rather than assuming that a brokerage available to a friend in the United States will be available to them.

This distinction is particularly important for people living permanently outside the United States.

Common Mistakes Nonresident Investors Should Avoid

Mistake 1: Using a fake U.S. address

Do not use a friend’s or relative’s U.S. address simply to get around residency restrictions.

Your brokerage application should accurately reflect where you actually live and your tax residency.

Mistake 2: Ignoring dividend withholding

A portfolio can generate attractive returns while still producing significant tax withholding on dividends.

Understand the applicable withholding rate before choosing a dividend-heavy strategy.

Mistake 3: Assuming capital gains are always tax-free

U.S. capital-gains rules for nonresident aliens can be favorable in some situations, but there are exceptions and your home country may tax the gains.

The IRS specifically identifies circumstances where capital gains of nonresident aliens can become taxable.

Mistake 4: Ignoring your home country’s tax rules

Opening a U.S. brokerage account does not necessarily eliminate tax obligations in your country of residence.

Your country may tax worldwide investment income, dividends or capital gains.

Mistake 5: Choosing a broker based only on $0 commissions

Trading commissions are only one component of your total investing costs.

For an international investor, foreign-exchange costs, transfers, spreads and tax treatment can matter just as much.

Can a nonresident alien open a U.S. brokerage account?

Yes, potentially. Several U.S. brokerages accept international clients, but eligibility depends on the investor’s country of residence, account type and other requirements.

What is the best brokerage for nonresident aliens?

For many international investors, Interactive Brokers is one of the strongest options because of its broad international availability and market access. Charles Schwab International can also be attractive for investors primarily interested in U.S. securities.

However, the best option depends on your country and investment objectives.

Can I buy U.S. stocks without living in America?

Yes. You do not necessarily need to live in the United States to invest in U.S.-listed stocks. The brokerage must accept residents of your country.

Do nonresident aliens pay tax on U.S. dividends?

Generally, U.S.-source dividends paid to nonresident aliens are subject to 30% withholding unless a lower treaty rate applies.

Do nonresident aliens pay U.S. capital gains tax?

Often, capital gains from U.S. securities are not subject to U.S. tax when the nonresident alien is in the United States for fewer than 183 days, but important exceptions exist.

What is Form W-8BEN?

Form W-8BEN is used by eligible foreign individuals to establish their non-U.S. status and, where applicable, claim treaty benefits for reduced withholding.

Is Interactive Brokers good for international investors?

Yes. Interactive Brokers is particularly notable for international investors because it accepts clients from many countries and provides access to a large number of global markets.

Final Verdict: Which U.S. Brokerage Is Best for a Nonresident Alien in 2026?

For many investors living outside the United States, Interactive Brokers is one of the strongest overall choices because of its international reach, broad market access and multi-currency capabilities.

Charles Schwab International is another excellent option for eligible residents who primarily want exposure to U.S. stocks and ETFs through an established U.S. brokerage.

However, the “best” brokerage isn’t necessarily the one with the lowest advertised commission.

Your decision should be based on:

Whether your country is supported
The securities you want to buy
Trading and currency-conversion costs
Deposit and withdrawal options
Tax documentation
Dividend withholding
Your country’s tax rules
Account minimums and requirements
Customer support
Whether the account type you want is available to nonresident aliens

If you live outside the United States and want to invest in U.S. markets, start by checking country eligibility and tax requirements before transferring any money.

The right international brokerage can give you access to some of the world’s largest companies and financial markets without requiring you to become a U.S. resident.
