Non-US residents who form US companies face a narrow banking field. Traditional US banks (Chase, Bank of America, Wells Fargo) increasingly require in-person signup and US SSN for verification. Fintechs fill the gap — and the top 4 options each have different trade-offs for non-residents.
Quick verdict
| Bank | Non-resident support | Setup timeline | Key strength |
|---|---|---|---|
| Mercury | Full | 3-7 business days | FDIC, Treasury yield, VC investor preference |
| Wise Business | Full | 2-5 business days | Multi-currency accounts (40+ currencies) |
| Brex | Limited (VC-backed startups primarily) | Varies | Best credit card alongside banking |
| Relay | Full (US entity required) | 3-5 business days | Multi-user access, bookkeeping integrations |
One-line verdict: Most non-US founders use Mercury + Wise Business together. Mercury for US-denominated checking and treasury; Wise for multi-currency receiving and FX.
Mercury — the default non-resident choice
Mercury explicitly supports non-US residents forming US companies. Requirements:
- US entity (LLC or C-corp, any state).
- EIN (obtained via Form SS-4).
- Government-issued ID from any country.
- Proof of business address (can be your registered agent's address — they accept this).
- Brief business description and expected transaction volume.
What non-residents actually get at Mercury
- US checking account with routing/account numbers for ACH and wire receipt.
- FDIC insurance via partner banks (currently up to $5M sweep network).
- Free domestic ACH, incoming and outgoing wires.
- Free international outgoing USD wires; FX margin on non-USD outgoing.
- Mercury Treasury (idle cash into money-market funds at 4-4.5% APY).
- Unlimited virtual cards for spending control.
- No monthly fees, no minimum balance.
Mercury approval rates for non-residents
Approval is high but not automatic. Denials cluster around:
- Founder from sanctioned or high-risk countries (based on current OFAC list).
- Business model unclear or ambiguous (crypto, adult, gambling, etc.).
- Business description that reads as "holding company" rather than active operations.
Mercury is particularly friendly to non-US SaaS founders, consultants, and e-commerce operators. Stripe Atlas-formed companies have an even faster approval path via Mercury's partnership.
Wise Business — the multi-currency layer
Wise Business is structurally different from Mercury — it's not a US bank; it's a UK-regulated money-movement platform. For non-US founders, Wise offers:
- Multi-currency receiving accounts. Get native account details in USD, GBP, EUR, AUD, SGD, HKD, CAD, NZD, JPY — so your international customers pay in their local currency.
- Near-zero FX margin. Convert between 40+ currencies at the mid-market rate + ~0.3-0.5% fee. Traditional banks charge 2-3%.
- Assets Earnings. Idle currency earns interest at ~3-4% depending on denomination.
- Batch payments. Pay 1,000 recipients from a CSV upload.
- API access. Most founder-friendly banking API in the space.
Wise limitations
- Not FDIC-insured. Safeguarded (segregated) instead — EU regulatory framework.
- No lending or overdraft.
- Not ideal as sole US banking if you're raising US VC (investors prefer Mercury).
Brex — the VC-backed startup card
Brex competes with Mercury on the tech-startup side. Non-resident support has tightened since 2022. Today, Brex accepts applications from:
- VC-backed startups (has raised from a US VC firm).
- YC companies or Tier 1 accelerator graduates.
- Certain high-revenue founders with verifiable business operations.
If you're a solo bootstrapped founder without fundraising history, Brex approval is uncertain. The Brex credit card product is excellent (no personal guarantee, rewards on SaaS / travel / dining). Not a primary checking choice for most non-residents.
Relay — the multi-user alternative
Relay is a US-domiciled business banking fintech that supports non-US residents with a US entity. Features:
- US checking + savings + FDIC insurance.
- Up to 20 virtual checking accounts for different expense categories.
- Multi-user access with role permissions.
- Strong QuickBooks and Xero integrations.
Relay is quieter than Mercury but growing. Good fit for teams with multiple operators who need shared access. Pricing comparable to Mercury (free base).
Setup playbook for non-residents
- Form a US entity. Delaware LLC or C-corp via Stripe Atlas, doola, Firstbase, or Northwest (+ DIY).
- Obtain EIN. Via the formation service or DIY Form SS-4 mail to IRS.
- Apply to Mercury. Typically 3-7 business days to approval. Be specific about business model; avoid vague language.
- Apply to Wise Business. Parallel application. Typically 2-5 business days.
- Get both accounts operational. Verify via small test wire; set up Stripe / PayPal / Amazon merchant accounts.
- Route your revenue. USD customer payments → Mercury. Non-USD international → Wise. Monthly sweep USD profits from Wise → Mercury for treasury.
- Add Stripe Atlas Issuing or Mercury Virtual Cards for expense management.
Common pitfalls for non-residents
- Applying to too many banks at once. Some banks check business entity's banking history. Concurrent applications can trigger extra review.
- Using personal address as business address. Use registered agent address for Mercury. Some banks flag residential addresses as red flag.
- Vague business description. "Technology company" is a flag. "SaaS for small business accounting automation, B2B subscription revenue" is clean.
- Funding patterns that look like money laundering. Large round-number wires from personal account in home country to US business account early on can trigger review. Fund incrementally and tie to specific expenses.
What about Payoneer?
Payoneer is another multi-currency payment platform. Pros: widely-accepted globally, integrates with Amazon, Upwork, Fiverr. Cons: higher fees than Wise, less clean UX. Worth holding if your payment flow requires it; not sufficient as primary banking.
FAQ
Can I open Chase / Bank of America as a non-resident?
Rarely, and typically requires an in-person visit to a US branch with US-issued government ID or SSN. Most non-residents who successfully open traditional US business banking did so during a visit to the US with a local SSN holder as a co-signer.
Do I need both Mercury and Wise?
For USD-only business: Mercury alone works. For international revenue: both. The combination is the dominant pattern.
What's the minimum balance for any of these?
Zero on Mercury, Wise, and Relay. No minimums, no monthly fees on the free tiers.
Can I get a credit card as a non-resident?
Mercury IO (their credit card product) requires revenue history. Brex Card for VC-backed startups. For most bootstrappers, US credit cards require a SSN or ITIN. The workaround: ITIN (takes 6-8 weeks via Form W-7) opens up Capital One Venture X and similar personal-credit-required cards.
