How do credit scores work in the US: Complete guide for expats

Building credit can be especially challenging for expats who have recently moved to the US. Because credit histories do not transfer between countries, newcomers often have to start from scratch. Establishing a solid credit profile can take several months or longer.

This guide explains how the US credit scoring system works, what factors affect your score, and practical steps you can take to improve it.

Overview of the US credit system 🇺🇸

Most countries have systems to assess the creditworthiness of residents. Lenders and other service providers use this information when deciding whether to offer credit, loans, or certain types of contracts.

Your credit score can affect both everyday activities and major financial decisions – from renting an apartment to financing a car – so maintaining a good score is important.

When you move to a new country, however, you will usually need to build your credit history from scratch. Credit histories generally do not transfer internationally, and providers typically want to see recent, local credit activity before approving applications.

The US credit system is based on both credit reports and credit scores. A credit report is a detailed record of your credit activity, including loans, credit cards, and other accounts opened in your name, as well as your payment history. Your credit score is a numerical summary of this information, reflecting how reliably you have managed credit over time.

Understanding credit scores in the US

There are three major credit bureaus in the US. They produce reports that are the basis for scoring models to calculate credit scores for individuals.

The two main scoring models are FICO and VantageScore (only accessible from the US). Both models use information from the credit bureaus and consider similar factors, but they use different formulas. Because of this, a person’s score can vary slightly between FICO and VantageScore.

Both FICO and VantageScore generally use a scoring range of 300 to 850, and scores are updated regularly as new information is added to your credit report.

FICO scoring

📂 Category	🎯 Score range	💡 Impact
Exceptional	800–850	Best interest rates; easy approval
Very good	740–799	Competitive interest rates; high approval chances
Good	670–739	Approval for most loans; slightly higher rates
Fair	580–669	Some loan denials; higher interest rates; lower credit limits
Poor	300–579	Frequent loan refusals; may need to use specialist services with limited credit options

VantageScore scoring

📂 Category	🎯 Score range	💡 Impact
Excellent	781–850	Best interest rates; easy approval
Good	661–780	Competitive interest rates; high approval chances
Fair	601–660	Some loan denials; higher interest rates; lower credit limits
Poor	500–600	Limited loan options; high interest rates
Very poor	300–499	Frequent loan refusals; may need to use specialist services with limited credit options

Credit bureaus and credit reports in the US

💡 The three major credit bureaus in the US are:

• Experian
• Equifax
• TransUnion

These companies collect and maintain information about consumers’ credit activity (e.g., payments, applications, debts, and bankruptcies). They use this information to create credit reports, which are then used to calculate credit scores. Credit bureaus collect information from:

• Lenders (banks, credit card companies, mortgage providers, auto lenders)
• Debt collection agencies
• Public records (such as bankruptcies)
• Companies that verify credit applications
• Landlords and utility companies

Each bureau can use the information from its report to generate a score using both FICO and VantageScore. This means that US consumers essentially have six slightly different (albeit similar) scores. Which one applies depends on the individual agency – for example, bank or credit card company – reviewing your credit application.

Why credit scores matter for expats in the US 🇺🇲

📌 Credit scores in the US are typically used for:

• Mortgage application and home buying requirements
• Credit card approvals and interest rates
• Personal loan access and terms
• Rental applications and security deposits
• Insurance premium calculations
• Utility deposits and service connections

Some US employers may also carry out credit checks for high-level finance or accountancy roles. These require written consent under the Fair Credit Reporting Act (FCRA) and don’t show credit scores, only debt, bankruptcy, and payment history. Several states, including California and New York, restrict these checks.

⚠️ If you have a poor credit score in the US, you may struggle when applying for some of the above, and interest rates are likely to be higher.

What affects your credit score?

📌 Your FICO score takes the following into account:

• Payment history (35%) – includes on-time payments, missed or late payments, bankruptcies, collections, and repossessions
• Debt burden (30%) – includes total debt, number of accounts with balances, and credit utilization (how much of your available credit you are using)
• Credit history length (15%) – a longer credit history generally helps your score
• Credit mix (10%) – having experience managing different types of credit (such as credit cards, car loans, or mortgages) can help your score
• New credit (10%) – includes recent credit applications and newly opened accounts (multiple recent applications can temporarily lower your score)

📌 VantageScore doesn’t break things down into specific percentages, however it assesses similar factors, such as:

• Payment history
• Total credit usage
• Credit mix and experience
• New accounts opened
• Payment behavior over the past 24 months

Factors not considered for credit score calculations include personal data (e.g., age, gender, ethnicity), income and employment details, address, and criminal record (unless a financial judgment is attached).

Starting with no credit history as an expat 🇺🇲

When you move to a new country, you will typically start with no credit history, even if you had excellent credit back home. This is true in the US, where new arrivals are often described as “credit invisible”. This doesn’t mean bad credit, just that you don’t have enough borrowing history in the US to generate a credit score.

This is because each country has its own scoring system, and credit bureaus usually don’t share consumer data across international borders. Some global financial institutions, for example multinational banks, may consider international history. However, most lenders will want to see several months of credit activity reported within the US.

How to build credit as an expat in the US

Although you won’t have a credit history when you first move to the US, that doesn’t mean you can’t make initial moves to start building a good score. This will mean quicker access to credit products, as well as potentially lower interest rates.

💡 Here are a few simple steps to help you build a good credit history when you first move to the US:

• Get a secured credit card: These cards, designed for people with no credit history, require a small refundable deposit (usually up to $500) which becomes your credit limit.
• Pay bills regularly and on time: Whatever bills you do have (e.g., rent, utilities, secured cards), be sure to pay them promptly – or even early if you can.
• Become an authorized user: If you have a trusted family member or partner with good credit, they may be able to add you as a user on their credit card to boost your score.
• Don’t apply for credit too often: Multiple credit applications can negatively affect your credit score, so it’s better to wait until you’ve built some history.
• Add eligible bills to your credit report: If you’re paying rent , utilities, or phone bills regularly, check to see if this data is reported to the major credit bureaus.

Timelines for building credit in the US as an expat 🗓️

The exact timeline for building good credit will depend on your individual circumstances. Below is a rough guide for what to expect as a new arrival in the US:

🗓️ Approx timelines for building credit as a new expat in the US
0-3 months	No credit score – Open a bank account, get a secured credit card, become an authorized user on someone’s account if possible
3-6 months	Pay bills regularly and on time, keep credit balances low, keep new credit applications to a minimum
6-12 months	Check your credit score, start making credit applications (but not too many in a short time period), continue with regular bill payments
12-24 months	Your credit score should now be well established with good management (excellent/very good/good) and you can start applying for higher-end credit and expecting better interest rates
2 years +	Check your score occasionally for errors and report fraud if you experience it

Types of credit and their impact

The following types of credit are usually reported to the US credit bureaus. Each can impact your credit score in a different way:

📂 Types of credit
Installment loans (e.g., bank loans, auto loans, or student loans)	Repaid through regular payments over a set period of time, usually with interest. The installment amounts generally stay the same. Missed payments can significantly lower your credit score.
Revolving credit (e.g., credit cards and retail store cards)	Typically involves a credit limit (the maximum you can borrow in advance), and minimum regular payments with interest. You can choose to pay above the minimum (e.g., pay off the full debt) at any time, which resets your limit and boosts your credit utilization score (how much of your limit you use).
Open credit (e.g., charge card or collection account)	Similar to revolving credit, but the outstanding balance typically has to be paid in full each month.
Variable-rate loans (e.g., variable rate mortgages)	These differ from other installment loans, as the interest rate fluctuates, meaning that monthly repayments can vary.

Using credit scores for major purchases

Many lenders in the US will check your credit score before approving credit. Here are some of the most common examples of purchases where your credit score will dictate your chances of approval as well as interest rates offered:

Examples of major purchases in the US
🏡 Getting a mortgage	Your credit score will determine whether your application is approved, as well as influencing interest rates and deposit amount requirements.
💳 Credit card applications	Premium cards with high spending limits usually require an excellent or very good credit score. If your score is low, you’ll be restricted to lower-tier products.
🏦 Personal loans	Your score will affect your chances of approval, the loan amount, interest rates, and terms of loan offer.
🚗 Car loans	If you want to buy a vehicle on credit, sellers will look at your credit history to set the terms, and may ask for full upfront payment if you don’t have a sufficient score.
Other purchases	These can include cell phone plans and insurance products, where your credit score can affect your premium rates.

Expats in the US may find that large or regular payments to cover the likes of mortgages or auto loans may involve sending money from overseas to US accounts. Wise can help you manage your international finances with low-cost transfers and currency conversions using the mid-market exchange rate with transparent fees.

There are additional discounts on larger transfers, and you can get help from a dedicated support team to make the process easier and smoother.

Credit score monitoring and improvement

You can get free weekly online credit reports from all three bureaus through AnnualCreditReport.com, the only website authorized by federal law for free credit reports. Under US federal law, you are entitled to at least one free credit report from each bureau every year. If you have trouble getting your free report, you can submit a complaint to the

Consumer Financial Protection Bureau.

💡 Your free credit report does not automatically include your credit score. However, you can check your credit score at no cost in several ways:

• myFICO – has a free service to track your Equifax FICO score (with limited updates)
• Experian – provides free access to your FICO score when you create an account
• Credit Karma – offers free VantageScore scores based on Equifax and TransUnion data
• Your bank or credit card company – many financial institutions now provide free credit score access to customers
• Non-profit credit counseling agencies – some agencies may review your credit as part of their services

Monitoring your credit in the US is considered a “soft inquiry” which may appear on your report but doesn’t affect your score. This means you can check your report and score at any time without penalty. Regularly reviewing your reports also helps you spot inaccuracies or signs of identity theft, such as accounts opened fraudulently in your name.

⚠️ To reduce risk, you can place a free fraud alert on your credit file, which encourages lenders to verify your identity before extending credit. You may also request a free credit freeze at any time, which blocks most new creditors from accessing your report until you lift it.

Credit for different expat situations

As an expat living in the US, there are many times when you might need to apply for credit. These could include:

• Applying for a student credit card as an international student, which often requires a credit check.
• Accessing rental accommodation or signing up for a mobile phone contract when you first arrive on a temporary resident visa.
• Building your long-term credit as a permanent resident so that you can access a wider range of financial products (e.g., mortgage) and secure lower interest rates.
• Maintaining credit in your home country as well as building credit in the US, if you are a digital nomad.

If you are an expat building credit in the US and managing finances across borders, Wise can make this cheaper and easier.

You can hold money in 40 currencies in a multi-currency account, and spend in 150 countries using a Wise Multi-Currency Card. For those sending money across borders, international transfers are low-cost and use the mid-market rate with no hidden fees.

Common credit mistakes expats make in the US

⚠️ Here are some common mistakes to avoid if you’re building credit as an expat in the US:

• Assuming your foreign credit history transfers – when you first move to the US, you’ll start off as “credit invisible” with no local credit history, so applying for loans or credit cards too early can lead to rejection.
• Not building credit early – you can develop your credit when you first move by applying for a secured credit card or becoming an authorized user on someone else’s card, which makes it easier to quickly boost your credit score.
• Carrying a high credit balance – if you use too much of your available credit, this can damage your long-term credit score.
• Applying for too much credit at once – a formal credit application is logged on your report as a “hard inquiry”, and too many of these in a short period can lower your credit score.
• Closing old credit accounts too soon – length of credit history affects your score, so closing old accounts as soon as you qualify for better ones can reduce your available credit.
• Not monitoring credit performance – some people fear that repeatedly checking their credit reports and scores will harm their credit rating, but these count as “soft inquiries” that don’t impact credit score.
