Opening a US Bank Account

Opening a U.S. bank account is one of the first things you need to tackle after arriving in America (see our guide: 10 Things to Do Right After Moving to the U.S.). Without one, you can't pay rent, receive a paycheck, apply for a credit card, or even pass some apartment background checks. Yet plenty of people walk into a branch fully intending to open an account — only to be turned away for missing paperwork, or leave confused about which account type they actually need.

This guide is written for Korean-Americans and Korean nationals in the early stages of U.S. life — immigrants, international students, and corporate transferees alike. Everything here reflects procedures and requirements as of 2025–2026. Because policies vary by bank and by state, always call your target branch ahead of time to confirm exactly what they need.

Checking vs. Savings: Which Account Do You Actually Need?

U.S. bank accounts fall into two main categories. A checking account is your everyday workhorse — debit card purchases, direct deposit, bill pay, and transfers all run through it. A savings account earns interest but may limit how many withdrawals you can make per month. The standard move is to open a checking account first, then add a savings account once you're settled.

The big national banks — Chase, Bank of America, Wells Fargo, and Citi — have the most branch and ATM locations, which is convenient, but most charge a monthly maintenance fee in the $12–$15 range (more on waivers below). Online-only banks like Ally, SoFi, and Charles Schwab typically have no monthly fees and often offer higher interest rates on savings. If you live in or near a Korean-American community, Korean-owned banks such as Hanmi Bank, Woori America Bank, and Shinhan Bank America are worth a serious look — they offer Korean-language service, competitive international wire rates to Korea, and staff who understand the documentation challenges immigrants face.

What Documents Do You Need — and Can You Open an Account Without an SSN?

The most common question we hear: "Can I open an account without a Social Security Number?" The short answer is: it depends on the bank. Some institutions — including Korean-owned banks and select Chase and Citi branches — will accept an ITIN (Individual Taxpayer Identification Number) or even just a passport plus visa in lieu of an SSN. Call ahead and ask directly.

Here's what banks generally require. Confirm the exact list with your branch before you go:

• Primary ID: Passport — the safest and most universally accepted option for non-citizens
• Secondary ID: U.S. driver's license, state-issued ID, or a foreign driver's license (accepted at some banks)
• Visa documentation: The visa page of your passport plus supporting documents such as an I-20 (F-1 students), DS-2019 (J-1), or approval notice for H-1B, L-1, etc.
• SSN or ITIN: If you don't have either yet, some banks will open the account and let you provide it later — ask upfront
• U.S. address verification: A lease agreement, utility bill, or school enrollment letter showing your U.S. address
• Opening deposit: Ranges from $0 to around $100 depending on the bank and account type; some accounts require a minimum balance to avoid fees

Step-by-Step: Opening an Account in Person

Online applications exist, but if you're a non-citizen or have non-standard documents, walking into a branch is far more reliable. Follow these steps:

• Step 1 — Pick your bank and account: Weigh branch access, monthly fees, and Korean-language support. Visit the bank's website and compare their checking account options side by side.
• Step 2 — Call ahead: Phone your target branch and ask whether they can open an account with foreign passport only, and get a confirmed list of required documents. Korean-owned banks can handle this call in Korean.
• Step 3 — Bring everything and show up: Pack your passport, visa documents, proof of address, and your opening deposit (cash or money order). No appointment is usually required, but branches in busy Korean neighborhoods can have long waits — aim to arrive right when they open in the morning.
• Step 4 — Fill out the application: A banker will walk you through the paperwork. Expect a ChexSystems identity check — this is standard and typically results in same-day approval.
• Step 5 — Get your account number and debit card: You'll receive your account number and routing number on the spot. Some branches issue a temporary debit card the same day; your permanent card arrives by mail in roughly 7–10 business days.

Budget about 30 minutes to an hour for the whole visit, including wait time. Your account is usually active the same day or the next business day. Expect to wait one to two weeks for your physical debit card.

Monthly Fees and Hidden Costs: What to Watch For

Unlike banks in Korea, many U.S. banks charge a monthly maintenance fee — typically $12–$15 per month for a standard checking account at a major bank as of 2025–2026. The good news is that most banks waive the fee if you meet certain conditions, such as setting up direct deposit or maintaining a minimum daily balance (often $500–$1,500). Always ask about waiver conditions before you sign anything.

Other costs to watch out for:

• Out-of-network ATM fees: Roughly $2.50–$3.50 per transaction
• International wire transfers: $25–$45 per transfer at most big banks
• Overdraft fees: $25–$35 per occurrence (some banks have eliminated these — worth asking)

If you send money to Korea regularly, using a fintech service like Wise (wise.com) or Remitly (remitly.com) alongside your bank account will save you significantly on transfer fees compared to a standard wire.

Tips Especially Useful for Korean-Americans

• Lean on Korean-owned banks: Hanmi Bank (hanmibank.com), Woori America Bank (wooriamericabank.com), and Shinhan Bank America offer Korean-language service, linked transfers to Korean accounts, and in some cases programs that recognize your Korean credit history. Branches are concentrated in LA, New York, New Jersey, Chicago, and Dallas.
• Student-specific accounts: If you're an international student, bring your student ID. Chase College Checking and similar programs at other major banks offer fee-waived accounts for students, often available at branches near university campuses.
• Apply for an ITIN in parallel: If you're on a visa that doesn't qualify you for an SSN (such as a tourist visa or certain non-immigrant visas), an ITIN opens up far more financial options. Apply with IRS Form W-7 at irs.gov — processing takes approximately 7–11 weeks.
• Start building credit right away: Once your account is open, apply for a secured credit card as soon as possible. A secured card requires a cash deposit as collateral and reports to the credit bureaus just like a regular card. Two to three years of on-time payments will make a real difference when you need to pass an apartment screening, finance a used car, or qualify for other credit products.

Common Mistakes — and How to Avoid Them

• Showing up without proof of address: This is the number-one reason people get turned away. If you just arrived and don't have a lease yet, ask in advance whether your school's I-20 or an enrollment letter will be accepted as a substitute.
• A negative ChexSystems record: If a previous U.S. bank account was closed due to overdrafts or fraud, your new application may be denied. Look for banks that offer "Second Chance Checking" — some credit unions and Wells Fargo's Clear Access Banking account are good places to start.
• Trying to open online with foreign documents: Non-U.S. addresses and passport information frequently cause online applications to stall or get rejected mid-process. If you're a non-citizen, go to a branch in person whenever possible.

Frequently Asked Questions

Q: Can I open an account on a tourist visa (B-1/B-2)?
Some banks — including Citi and certain Korean-owned banks — will work with tourist visa holders, but most major banks prefer to see a long-term visa. Call the branch first; policies vary widely by location.

Q: What's the best way to send money to Korea after I open my account?
Bank wire transfers are convenient but expensive ($25–$45 per transfer). Wise and Remitly both offer significantly lower fees and competitive exchange rates. Korean-owned banks also tend to offer their own Korea-specific transfer services that are worth comparing.

Q: If I move back to Korea, what happens to my account?
As long as a valid U.S. mailing address is on file and you meet any minimum balance requirements, the account can stay open. That said, prolonged inactivity can trigger dormancy fees or account closure, so notify your bank before you leave and ask what their policy is.
