Mercury vs Wise vs Relay vs Rho: Which Approves Non-Residents

Opening a US business bank account as a non-resident comes down to which provider actually reviews foreign-owned LLCs favourably. Here is how Mercury, Wise, Relay and Rho compare in practice.

Why this comparison keeps coming up

Every founder who forms a US LLC from Europe eventually hits the same wall: which bank will actually open an account for a company with no US owners, no US address, and no US credit history? Mercury, Wise, Relay and Rho all serve startups, but they were not built for identical customers, and their underwriting for non-residents differs more than their marketing pages suggest.

None of these providers can guarantee approval for any specific applicant. Underwriting depends on your industry, country of residence, the completeness of your LLC paperwork, and how your application is presented. What follows is a realistic picture of how each one tends to treat non-resident, foreign-owned LLCs, based on their published requirements and general onboarding patterns.

Mercury vs Wise vs Relay vs Rho at a glance

Mercury: the common starting point

Mercury is usually the first name non-resident founders hear, and it remains a reasonable default. It does not require an SSN or ITIN, and applications are reviewed with an EIN, formation documents, passport, and proof of address. Mercury has become more selective over the past couple of years, restricting some higher-risk countries and industries, and it sometimes asks for evidence of a genuine US connection, such as a US customer base, a US co-founder, or a clear business reason to operate through a US entity. A well-documented LLC with a complete Form SS-4 EIN, a real business description, and consistent information across your application still tends to fare best.

Wise Business: the pragmatic backup

Wise is not a bank, it is a licensed payments institution, but for many non-resident founders that distinction barely matters day to day. It issues US account details that can receive ACH and wire payments, supports multiple currencies in one account, and its onboarding has generally been more consistent across a wider range of countries than a traditional bank. The tradeoff is that Wise is not a full banking relationship, so features like domestic wire flexibility, cheque deposits, or building a US credit profile through a card programme are more limited. Many founders use Wise Business alongside another provider rather than as the sole account.

Relay: strong if you already have an ITIN

Relay is built for US small businesses that want multiple sub-accounts and easy card issuing for a team. It generally leans toward a US business banking model, which for non-resident owners often means expecting an SSN or ITIN tied to a beneficial owner. If you are actively getting an ITIN as part of setting up your LLC anyway, Relay becomes far more workable once that number exists. Without it, approval is less predictable.

Rho: built for scale, not for day one

Rho targets startups that already have some traction, funding, or transaction volume, and pairs banking with treasury and spend management tools. Its underwriting tends to be more manual and relationship-driven than Mercury or Wise, which can work against a brand-new, pre-revenue LLC with a solo non-resident founder. Rho is worth revisiting once your company has real activity, a US address, and a case to make for treasury features, rather than as your first account.

What actually improves your odds, regardless of provider

• Get your EIN properly through Form SS-4 before applying anywhere. Fintechs check that the EIN matches IRS records.
• Use a real, verifiable US business address rather than a generic mail drop with no other footprint.
• Keep your business description, website, and application answers consistent. Mismatches trigger manual review or decline.
• Apply for an ITIN if your longer-term plan includes Relay, opening physical branch accounts, or building US credit history.
• Do not apply to every provider simultaneously. Multiple rapid applications with the same details can look like account farming.

Founders Credit sets up the LLC, EIN, ITIN, and the bank account application as one coordinated process rather than separate DIY steps, which is usually the difference between a clean approval and a frustrating back-and-forth with support.
