How to Build US Credit as a Foreigner from Uruguay

Uruguay founders expanding into the United States frequently encounter the invisible-credit problem. When relocating or launching a US-based startup, founders realize that their robust local credit history established with Uruguay's central risk registry managed by the Central Bank of Uruguay (Banco Central del Uruguay - BCU) or private bureaus like Equifax Uruguay does not transfer across borders [1] [2]. Because US financial institutions rely entirely on domestic credit scoring models operated by bureaus such as Equifax, Experian, and TransUnion, foreign founders start with a blank slate, complicating efforts to secure corporate credit cards, office leases, or operational financing without personal guarantees.

Why US credit matters

A US credit file changes what a US company can do. Without one, financing means cash collateral or a personal guarantee, corporate cards come with a deposit, and commercial leases ask for six months up front.

With one, the same company borrows at a normal rate. That is the whole difference, and it is why the sequence below is worth the months it takes.

No part of this is guaranteed. Credit decisions belong to lenders, and nobody — including us — can promise you a score or a limit.

The Amex Global Transfer route

American Express runs a programme — Global Transfer, sometimes called the Global Card Relationship — that lets an existing Amex cardholder apply for a US card using their established relationship with Amex rather than starting from nothing.

Your credit history does not transfer. This is the most common misunderstanding about the programme. What transfers is the relationship — Amex's own record of how you have handled your account with them. Your local bureau file, your repayment record with other lenders and your local credit score do not cross the border. Amex US underwrites you as a new customer who happens to be a known quantity to Amex.

That is still a considerable advantage over building a US file from zero. It is not the same as arriving with a credit history.

Four conditions apply, and all four must be met:

1. The card you already hold must be issued by American Express itself, not by a local bank operating under an American Express licence.
2. You must be the primary cardholder, not an additional or supplementary cardholder.
3. You must have held the card for at least three months.
4. The account must be open and in good standing when you apply.

Corporate cards are excluded separately from all four.

Condition one eliminates more applicants than the other three combined. In many markets American Express operates through Global Network Services, where a local bank licenses the Amex brand and issues its own cards under it. Those cards carry the Amex logo, but the account relationship belongs to the bank — so there is nothing to transfer. A local partnership is not an alternative route to eligibility; it is the thing that removes it.

How to check your own card: read the cardholder agreement, not the card. The agreement names the legal entity that issued it. If that name is a local bank, the card will not qualify. If it is an American Express entity, it may. If you cannot find the agreement, call the number on the back and ask which legal entity issued the card.

The ITIN Path

For founders who cannot utilize the American Express Global Transfer pathway, securing an Individual Taxpayer Identification Number (ITIN) serves as the foundational step for entering the US financial system. An ITIN allows foreign nationals to open US bank accounts, file taxes, and apply for select unsecured credit cards designed for non-residents.

1. Form W-7 Preparation: Complete IRS Form W-7 with accurate identification details, ensuring that all supporting documentation meets strict IRS validation standards.
2. Certified Acceptance Agent (CAA) or Certifying Acceptance: Gather an original passport or certified copies issued by the issuing agency to verify identity and foreign status. Utilizing a certified acceptance agent in Uruguay or a US-based firm expedites verification without surrendering physical passports to the IRS.
3. Submission to the IRS: Mail or submit the completed Form W-7 package alongside a federal income tax return or qualifying withholding document, unless an exception applies under specific tax treaty provisions.
4. ITIN Issuance: Receive the official IRS correspondence assigning the nine-digit ITIN, typically within six to ten weeks of submission.
5. Secured Card Application: Apply for secured credit cards or non-resident banking products using the newly acquired ITIN and a US mailing address or registered agent service.

Nova Credit

Nova Credit bridges international financial borders by translating foreign credit histories into equivalent US credit bureau scores [4]. While Nova Credit maintains extensive partnerships across numerous global jurisdictions—including Canada, Brazil, India, the United Kingdom, Mexico, and Australia—coverage for Uruguay is not currently supported through direct bureau integrations [4]. Founders from Uruguay must therefore rely on alternative bootstrap mechanisms, such as secured credit cards or authorized user accounts, rather than direct cross-border credit translation.

Business Credit: The Faster Lane

Building corporate credit independent of personal credit history offers an effective strategy for mitigating personal exposure. By obtaining an Employer Identification Number (EIN) for a US LLC or C-Corp and establishing a dedicated business bank account, founders can interact with commercial vendors that report payment activity to major business credit bureaus, including Dun & Bradstreet, Experian Business, and Equifax Business. Securing a Dun & Bradstreet D-U-N-S number enables startups to build a robust D&B Paydex score by maintaining 30-day or 60-day payment terms with trade suppliers, allowing the enterprise to qualify for commercial credit lines without relying solely on the founder's personal credit history.

Recommended Sequence

1. Form the US Entity: Establish a Delaware C-Corp or LLC and obtain an official Employer Identification Number (EIN) from the IRS.
2. Secure an ITIN: File IRS Form W-7 to acquire an Individual Taxpayer Identification Number if personal US credit products are required.
3. Leverage Amex Global Transfer: Apply for a US American Express card using existing Uruguayan Amex history if an eligible account is active [3].
4. Open a US Business Bank Account: Partner with fintech platforms or traditional banks that cater to international founders to establish commercial banking relationships.
5. Build Business Credit: Register for a D-U-N-S number and open vendor accounts that report payment history to Dun & Bradstreet and Experian Business.
