Opening a US business account as a non-resident is a remote, document-driven process — but the order matters and the address rules trip people up. Here is the step-by-step, the exact documents you will need, and the most common reasons applications get rejected (and how to avoid them).

How to open a fintech account, step by step
The order of these steps matters, because the fintech's know-your-business checks validate your application against your state filing and your IRS record. If the entity or EIN does not yet exist, the application cannot pass.
Work through the sequence below at your own pace. Follow-up document requests are normal; answering them quickly and clearly is often the difference between a smooth approval and a stalled one.
- 1. Form a US LLC or C-Corporation in your chosen state.
- 2. Obtain an EIN from the IRS (non-residents without an SSN/ITIN apply by fax or mail on Form SS-4, not online).
- 3. Secure a real US business street address (not just a registered-agent address).
- 4. Choose a non-resident-friendly fintech and gather your documents.
- 5. Apply fully remotely, describing your business clearly and accurately.
- 6. Respond promptly to any KYC follow-up; expect roughly 1-5 business days for review, sometimes faster, sometimes longer.
Documents you will need
Requirements fall into five buckets. Exact items vary by provider and change over time, so treat this as illustrative and confirm the current list at application. An operating agreement is commonly requested by fintechs and is typically required for a traditional in-person bank account.
- State formation document — Articles of Organization, Certificate of Formation, or Articles of Incorporation.
- EIN proof — the IRS CP-575 confirmation letter, a 147C verification letter, or an IRS-returned/stamped SS-4 (not a blank application).
- Government photo ID / passport for every owner holding 25%+ and for the control person.
- Proof of address — your personal/home address, and increasingly a real US business address.
- Beneficial-ownership and business-activity details — who owns and controls the company, plus a clear description of what it does (a website helps).
- Operating agreement — commonly requested by fintechs; usually required for in-person branch accounts.
Why applications get rejected, and how to avoid it
Most denials come down to a handful of avoidable issues. Knowing them in advance saves weeks.
A very common pattern for companies formed through services that use a registered-agent address is that the Secretary of State record and EIN letter show the registered-agent address, while the founder types a different virtual-office address into the application. The know-your-business check flags the inconsistency. Keep your addresses consistent, use a genuine US business address that providers accept, and describe your business honestly and specifically. Never misrepresent your identity or address to qualify — beyond being against provider terms and the law, it is exactly what these checks are built to catch.
- Address flagged as a registered-agent address, PO box, or CMRA/mailbox.
- Mismatch between the address on your state filing / EIN letter and the address in the application.
- Incomplete or slow responses to follow-up document requests.
- Vague, generic, or implausible business description.
- Residency in an OFAC-sanctioned or otherwise restricted country (causes automated denials).
