The Three Banking Tiers for Non-Residents

Tier 1: Chartered US banks

Mercury, Relay, Brex. Chartered US banks with FDIC partner coverage. Full integration with US payment systems (ACH, wire, Stripe, debit cards).

Pros: FDIC coverage, Treasury yield, mainstream payment processor integration, debit cards with spend controls. Cons: Lower approval rates for non-residents (50-70%), category restrictions (crypto exchanges, gambling, MSB all rejected).

Best for: SaaS, agency, e-commerce, services businesses where the country profile clears (~70%+ approval expected).

Tier 2: Money services providers

Wise Business, Payoneer, Airwallex. Money services (not chartered banks). Provide USD accounts with US routing and account numbers but custodial structure (no direct FDIC).

Pros: Broader acceptance (85-95%), multi-currency support, lower FX fees. Cons: No FDIC, no Treasury yield, may have feature limitations.

Best for: Fallback when Tier 1 rejects, international clients billing in EUR/GBP/AUD, marketplace payouts (Upwork, Fiverr, Amazon).

Tier 3: Crypto-friendly banks

Custodia Bank, BankProv. Specialized for digital asset businesses. Accept crypto exchanges, NFT marketplaces, and other crypto-native operations that Tier 1 banks reject.

Pros: Approve crypto businesses, support USDC and stablecoin operations. Cons: Higher fees, narrower features, smaller integration ecosystem.

Best for: Crypto exchanges, DeFi operators, NFT marketplaces, Web3 protocol operators.

How to sequence your applications

If country profile is high-tier (UK, EU, Singapore): Mercury first, Relay second, Wise fallback.
If country profile is mid-tier (India, UAE, Brazil): Mercury first, then Wise.
If country profile is tightened (Pakistan, Nigeria, Vietnam): Wise first, Mercury stretch.
If business is crypto-related: Wise primary, Custodia secondary. Mercury usually rejects.
If revenue is $100K+/year: Add Brex to the stack.

Combined success rates

Across our 800-application intake, combined success rate (Mercury + Relay + Wise) is ~99%. Almost every non-resident founder ends up with at least one US-side banking option. The sequencing matters more than the individual bank choice.

Frequently asked questions

Is FDIC really important for small operating LLCs?

For balances under $250K, FDIC coverage matters less day-to-day. For larger Treasury holdings ($500K+), Tier 1 chartered banks with FDIC partner coverage are safer.

Can I just use Wise Business and skip Mercury?

Yes, especially if your country profile is tightened. Wise handles most non-resident operations. Mercury's Treasury yield is the main feature you would miss.

Why not start with Tier 3 (crypto banks)?

Higher fees, narrower features. Only worth it for crypto-specific businesses. For SaaS, agency, e-commerce, Tier 1 or Tier 2 is the right starting point.

Do banks talk to each other?

Banks share some information through credit bureaus and risk databases but generally each bank reviews independently. A rejection at Mercury does not directly hurt your Wise application.
