Fidelity, Charles Schwab, and Vanguard are often compared as if every investor can choose among all three on equal terms.
For a newcomer to the U.S. financial system, that assumption can be wrong.
A permanent resident, an F-1 student, an H-1B worker, a U.S. citizen who later moves abroad, and a person who already lives outside the United States can face different account-opening or account-maintenance rules—even before fees, apps, or fund choices enter the picture.
The useful comparison is not “Which broker is best?” It is: Which of these firms will serve your actual residency status, and what practical differences remain after eligibility is confirmed?
Verified: September 11, 2026. This article compares current published information from Fidelity, Charles Schwab, and Vanguard. Brokerage eligibility, cash yields, fees, and product features can change.
Quick comparison: eligibility comes before features
| Question | Fidelity | Schwab | Vanguard |
|---|---|---|---|
| New customer living outside U.S. | No new relationship for prospective customers residing outside the U.S. | Schwab International may be available in qualifying countries | U.S. retail account-opening page directs people living/working abroad to Vanguard’s international site |
| U.S. citizen / permanent resident requirement | Public general brokerage guidance does not present the same blanket citizenship/permanent-resident rule as Vanguard; application eligibility must still be verified | U.S.-resident and international pathways differ; Schwab directs international employees living in the U.S. to the U.S.-resident account path | U.S. citizen or legal permanent resident with U.S. mailing address required on Vanguard’s current account-opening page |
| Fractional investing | U.S. stocks and ETFs from $1 | Most U.S.-listed stocks and ETFs from $1 | Vanguard ETFs from $1; other products follow their applicable purchase rules |
| Default / settlement cash | SPAXX can serve as a core cash position; 7-day yield was 3.34% on Sep. 7, 2026 | Default uninvested brokerage cash was 0.01% APY on Schwab’s current cash page; higher-yield money funds require a separate purchase in most accounts | VMFXX is available as a brokerage settlement option; 7-day SEC yield was about 3.62%–3.63% in early Sep. 2026 |
| Account minimum | $0 for the standard retail brokerage account | $0 for a standard Schwab brokerage account | $0 to open a brokerage account |
Do not read this table as an approval guarantee. Broker-dealers may request additional identification and can apply account-specific compliance rules.
1. The biggest newcomer difference may be eligibility—not cost
All three firms advertise low-cost U.S. investing. But they do not publish the same account-opening rules.
Vanguard has the clearest citizenship/permanent-resident restriction
Vanguard’s current “How to open an account” page says an applicant needs to be a U.S. citizen or legal permanent resident with a U.S. mailing address.
That has a direct consequence for many temporary visa holders. An F-1 student or H-1B worker who has not become a legal permanent resident should not assume that a U.S. residential address alone makes a new Vanguard retail brokerage account available.
This is a meaningful difference from a generic “Fidelity vs. Schwab vs. Vanguard” comparison because a platform that is attractive on funds or settlement cash is irrelevant if you cannot open the account.
Fidelity’s published restriction is especially clear after you move outside the U.S.
Fidelity states that it does not open accounts for new prospective customers who reside outside the United States.
Fidelity’s general brokerage-opening guidance says that applicants are typically asked for information such as a Social Security number, residential address, employment information, and identity documentation. However, the public pages reviewed for this article do not provide a simple blanket statement that every temporary visa category is accepted.
For a non-U.S. citizen living in the United States, the safest approach is therefore to confirm current eligibility with Fidelity rather than infer approval from age, address, or tax ID alone.
Schwab separates U.S.-resident and international pathways
Schwab’s standard U.S. brokerage page asks for information such as a Social Security number and says there is no account minimum.
Separately, Schwab operates an international brokerage pathway for qualifying residents outside the United States. Schwab’s own equity-account guidance also tells an international employee who is currently living in the United States to use the U.S.-resident account path.
That distinction is useful: Schwab treats where you live as a major operational fact rather than assuming every non-U.S. citizen belongs in an international account.
If you are a visa holder living in the U.S.
Do not choose among Fidelity, Schwab, and Vanguard from a generic broker ranking. First check each firm’s current account-opening rules for your exact immigration, tax-ID, and residency situation. For app-focused eligibility, see our Robinhood vs. SoFi vs. Webull guide for visa holders.
2. Uninvested cash can create a much larger difference than a $0 trading commission
For a beginner, it is common to transfer money into a brokerage account and leave some of it uninvested while deciding what to buy.
That makes the brokerage’s cash treatment surprisingly important.
Fidelity: SPAXX can put idle cash into a government money market fund
Fidelity currently advertises its Government Money Market Fund, SPAXX, as an option for uninvested brokerage cash. The fund’s published 7-day yield was 3.34% as of September 7, 2026.
A money market fund is an investment product, not an FDIC-insured bank deposit, and its yield changes. But the practical point is that a new investor does not necessarily have to manually move idle brokerage cash into a separate high-yield product to earn a market-linked money-market yield.
Schwab: default cash is low-yield, but higher-yield money funds are available separately
Schwab’s current cash-investments page lists 0.01% APY for uninvested cash in a standard brokerage account.
At the same time, Schwab offers separately purchased money market funds with much higher yields. As of September 9, 2026, several retail government and Treasury money funds were around the mid-3% range.
This means a Schwab customer needs to understand an important operational detail:
“Cash at Schwab” and “a Schwab money market fund” are not the same thing.
For most new and existing accounts, Schwab says it has eliminated automatic money-market sweeps as the designated cash feature. If you want a higher-yielding money fund, you generally need to purchase it rather than assume idle cash will automatically earn that rate.
Vanguard: settlement cash can sit in a money market fund
Vanguard uses a settlement fund inside its brokerage account. Vanguard identifies the Federal Money Market Fund, VMFXX, as a settlement option, and the fund’s 7-day SEC yield was approximately 3.62%–3.63% in early September 2026.
Again, that yield is variable and a money market fund is not the same as an FDIC-insured savings account. But for someone who frequently holds cash between trades, the settlement structure can materially change how much idle money earns.
A simple $20,000 cash example
Suppose you transfer $20,000 to a brokerage account and leave it uninvested for three months while deciding how to invest.
Using a rough annualized comparison of 3.34%, 0.01%, and 3.63%—without compounding and before taxes—the approximate three-month income would be:
| Illustrative cash rate | Approx. 3-month income on $20,000 |
|---|---|
| 3.34% | about $167 |
| 0.01% | about $0.50 |
| 3.63% | about $181.50 |
This is not a forecast and the quoted yields can change daily. The example simply shows why cash handling can matter more than comparing three brokers that all advertise $0 online U.S. stock/ETF commissions.
3. Fractional shares are now more similar—but not identical
Old brokerage comparisons can become stale quickly because fractional-share programs have expanded.
Fidelity
Fidelity currently allows fractional purchases of U.S. stocks and ETFs starting at $1.
Schwab
Schwab now publishes fractional investing in most U.S.-listed stocks and ETFs starting at $1. This is broader than older descriptions of Schwab Stock Slices that focused mainly on S&P 500 stocks.
Vanguard
Vanguard allows dollar-based fractional investing in Vanguard ETFs from $1. Vanguard’s investment-product page says stocks and non-Vanguard ETFs follow the applicable market-share purchase rules rather than the same universal $1 Vanguard-ETF rule.
So what? If you invest small fixed dollar amounts into individual stocks or many different ETFs, Fidelity and Schwab currently provide broader published fractional-share flexibility. If your plan is primarily Vanguard ETFs, Vanguard’s $1 dollar-based trading removes much of the old share-price barrier.
4. Vanguard’s low-cost reputation does not mean every account is automatically fee-free
Vanguard currently lists a $25 annual account service fee for brokerage accounts, but says the fee can be avoided by signing up for electronic delivery of account documents.
That is not a reason by itself to reject Vanguard. It is simply a detail a newcomer can miss if they assume “low-cost funds” means “no possible account fee.”
Fidelity’s standard retail brokerage account advertises no account fee to open the account. Schwab’s standard brokerage account also has no account minimum.
5. If you may leave the United States, the comparison changes again
This is one of the most important questions for international workers and students.
Fidelity explicitly says that customers who later reside outside the United States can face product and service restrictions, including restrictions on buying mutual funds. New prospective customers already residing outside the U.S. cannot establish a new Fidelity relationship.
Schwab has a separate international platform for qualifying countries, so a move may involve a different servicing path depending on destination and account type.
Vanguard’s U.S. retail materials state that products and services on the U.S. site are intended for U.S. residents and direct non-U.S. investors to its international resources.
Therefore, if an international student or worker expects to leave the U.S. in a few years, ask this before opening an account:
“If I become a resident of [country], can I keep this account, continue buying securities, and maintain the same products?”
If you already live outside the United States, use our separate brokerage eligibility comparison for non-U.S. residents. That article compares international-account pathways rather than domestic U.S. retail brokers.
Which broker should a newcomer investigate first?
Rather than naming a universal winner, use your actual situation.
| Situation | What deserves attention |
|---|---|
| Temporary visa holder | Confirm eligibility first. Vanguard’s published new-account rule requires citizenship or legal permanent residency; do not assume the three firms are equally available. |
| New permanent resident | All three may deserve comparison; then focus on cash treatment, fractional investing, funds, tools, and whether you expect to move abroad. |
| Investor who often holds idle cash | Understand Fidelity’s core money-market position, Schwab’s low default sweep plus separately purchased money funds, and Vanguard’s settlement-fund structure. |
| Small-dollar stock/ETF investor | Fidelity and Schwab currently publish broad $1 fractional investing; Vanguard’s $1 program is centered on Vanguard ETFs. |
| Likely to move outside the U.S. | Ask about post-move servicing restrictions before choosing. Your future country of residence may matter more than today’s app features. |
Three mistakes to avoid
1. Treating “U.S. resident” and “U.S. citizen” as the same thing
A person can live in the United States without being a U.S. citizen or permanent resident. Vanguard’s published requirement shows why that distinction matters.
2. Ignoring cash because all three brokers have $0 stock commissions
Default cash treatment can create a much larger dollar difference than a commission that is already zero for common online U.S. stock and ETF trades.
3. Choosing only for today’s U.S. address
If your life is likely to cross borders, account portability and post-move restrictions should be part of the original decision.
Bottom line
Fidelity, Schwab, and Vanguard are all major low-cost investment firms, but they are not interchangeable for newcomers.
For a temporary visa holder, eligibility may eliminate one or more choices before feature comparison begins. For an eligible U.S. resident, uninvested-cash treatment and fractional-share availability can create meaningful practical differences. And for anyone likely to leave the United States, future account restrictions can matter more than which app feels easiest today.
That is why KoruVest does not name one of these firms “best” for every beginner. The right comparison starts with your residency and account eligibility, then moves to the features that affect how you will actually use the account.
