You have landed. You have a job offer, or a place at a university, or a cousin's spare room and a plan. And then you walk into a bank branch, ask to open a checking account, and someone behind a desk tells you that you need a Social Security number first.
That sentence has cost immigrants an enormous amount of money. People spend months cashing paychecks at check-cashing stores that take two or three percent off the top. They carry rent money in cash. They pay wire fees to send money home through storefront operators because they have no account to send from. All of it on the basis of a requirement that, in federal law, does not exist.
This guide sets out what the rule actually says, what a bank is really allowed to ask for, which documents work, and what to do when a branch still says no.
The rule that governs this
Banks in the United States run something called a Customer Identification Program. It comes out of the USA PATRIOT Act and sits in the Code of Federal Regulations at 31 CFR 1020.220. Every bank has one. It is the reason you are asked for identification at all.
The regulation lists the four pieces of information a bank must collect before opening an account: your name, your date of birth, your address, and an identification number.
That last one is where the confusion lives. The rule treats US persons and non-US persons differently, and it does so explicitly.
For a US person, the identification number must be a taxpayer identification number. That means a Social Security number, or in some cases an employer identification number.
For a non-US person, the regulation allows any one of the following:
- a taxpayer identification number;
- passport number and country of issuance;
- alien identification card number; or
- the number and country of issuance of any other government-issued document evidencing nationality or residence, and bearing a photograph or similar safeguard.
Read that list again. A passport number is sufficient on its own. The regulation puts it there as an alternative to a taxpayer identification number, not as a supplement to one. A bank that opens an account for a non-US person using a passport number and country of issuance has met its obligation under the rule.
This is the single most useful thing to know when you walk into a branch.
So why do banks keep asking for a Social Security number?
Because the regulation sets a floor, not a ceiling. A bank may impose stricter requirements than the law demands, and many do.
The reasons are mostly commercial rather than legal:
Credit decisions. If a bank wants to offer you a credit card, an overdraft line or a loan, it will want to pull a credit file, and the credit bureaus key on a Social Security number or an ITIN. For a plain checking or savings account with no credit attached, this reason evaporates — but the systems were often built once and never unpicked.
Interest reporting. If an account pays interest, the bank has to report that interest to the IRS, which means it needs a taxpayer identification number. A non-interest-bearing checking account does not create that obligation. This is why some banks will open a basic checking account on a passport but not a savings account.
Software. A great many account-opening screens have a mandatory SSN field because whoever specified the system in 2006 assumed every customer would have one. The person in front of you cannot override it. This is not a policy decision anybody made deliberately; it is a form that will not submit.
Risk appetite. Some banks have simply decided that non-resident customers are more trouble than they are worth, and have written policies to match.
None of these is the law. All of them will stop you at a particular branch of a particular bank. The practical consequence is that this is a bank-shopping problem, not a legal one.
What an ITIN is, and when you actually need one
An Individual Taxpayer Identification Number is issued by the IRS to people who have a US tax filing obligation but are not eligible for a Social Security number. It is nine digits, formatted like an SSN, and always begins with a 9.
An ITIN is a tax number. It is not work authorisation, it is not immigration status, and applying for one does not put you on any immigration list — the IRS and immigration enforcement are separate.
You need an ITIN if you have US income to report and no SSN. You do not need one simply to hold a checking account, though having one widens your options considerably, because an ITIN satisfies the "taxpayer identification number" limb of the rule and slots neatly into the bank's existing software.
The practical order of operations for most people is:
- Open a basic account on a passport, if you can find a bank that will do it, so you have somewhere to put your money now.
- Apply for an ITIN when you have a filing requirement, using Form W-7 submitted with your tax return, or through an IRS-authorised Certifying Acceptance Agent if you do not want to post your passport.
- Add the ITIN to the account once it arrives, which usually unlocks savings products and sometimes a secured card.
Trying to do all three at once is what makes the process feel impossible.
The documents that actually work
Walk in with more than you think you need. A branch that would have refused one document will often proceed on three.
Passport. The single most useful document. Unexpired, with the photo page clean and legible. If it carries a US entry stamp or visa, better still.
A second photo ID. A national identity card from your home country, a consular identification card, or a foreign driving licence. Many banks have a "one primary, one secondary" rule and this satisfies the second slot.
Proof of address. A utility bill, a lease, a letter from an employer, a bank statement from your home country showing a current address. Some banks will accept a letter from a landlord. If you are staying with family, a bill in their name plus a signed letter sometimes works; it depends entirely on the branch.
Visa or immigration document. An I-94 record, a visa page, an employment authorisation document, a student I-20. Not required by the regulation, but it answers the question that is actually bothering the person opposite you — whether you are going to be here long enough to be worth the paperwork.
ITIN letter, if you have one. The IRS assignment notice.
A note on the address requirement: the rule requires a residential or business street address. A post office box alone will not satisfy it. If you genuinely have no fixed address yet, the regulation permits an "address of next of kin or another contact individual" for a person with no residential address — but you will have to find a branch that knows that provision exists.
Which kinds of bank say yes
Rather than naming specific institutions, whose policies change without notice, it is more useful to understand the categories.
Large national banks. Mixed. Several of the biggest will open accounts on a passport plus a second ID, and have trained staff in branches in areas with large immigrant populations. The same bank may refuse you at a branch twenty miles away where the staff have never processed one. If you get a no, try a different branch of the same bank before giving up on it.
Community banks and credit unions. Often the best bet, particularly those with a stated community development mission. Credit unions require you to be eligible for membership, which usually means living or working in a particular area or belonging to an associated organisation, but membership is frequently easier to obtain than people expect. Decision-making is local, which cuts both ways: a manager who understands the rule can simply say yes.
Banks that advertise to your community. If a bank has signage in your language, it has a process for this. That is not a marketing accident.
Online banks and fintechs. Increasingly workable, and improving, but read the terms carefully. Many fintech products are not banks themselves; they are programmes running on a partner bank's licence, and the deposit insurance passes through that partner. Some require an SSN at sign-up regardless of what the regulation permits, because their onboarding is automated and the identity-verification vendor they use keys on an SSN.
What to do when they say no
Ask what specifically is missing. "We need a Social Security number" and "our system requires a taxpayer identification number to open an interest-bearing account" are different statements with different solutions. The second one is solved by asking for a non-interest-bearing checking account instead.
Ask for the branch manager. Not as a confrontation — tellers are often working from a one-page summary rather than the policy itself. A manager can usually see the full Customer Identification Program document and the exceptions in it.
Ask whether the bank's CIP permits a passport number for a non-US person. Phrasing it that way signals that you know what you are talking about, and it asks a question the bank can actually answer from its own documents rather than from memory.
Try another branch, then another bank. This is not a legal appeal process. It is a search. People routinely succeed at the fourth bank after three refusals, with exactly the same documents.
Consider an account at a bank in your home country with US capability. Some international banks will open a US account for an existing customer as part of a relocation service, with the identity work done before you travel. If your home bank has a US presence, ask before you leave.
A 2026 development worth knowing about
Banking supervision in this area has been moving. In August 2025 FinCEN issued an order dealing with taxpayer identification number collection at account opening, and in June 2026 it published an advisory concerning non-work-authorised populations.
The practical effect for an ordinary customer is subtle but real: compliance departments have been paying closer attention to this category of account, which has made some banks more cautious and others more careful to document that they are following the rule correctly. If you are refused and the reason given is vague, it may be that the branch has had recent internal guidance and is applying it conservatively.
None of this changes 31 CFR 1020.220. The passport provision is still there and still says what it says.
Building a credit record once the account is open
An account is the gateway, not the destination. Without a credit file you will be refused a phone contract, an apartment, a car loan and a credit card, and will be asked for deposits that assume the worst about you.
A secured credit card is the standard route. You deposit, say, five hundred dollars; the bank issues a card with a five-hundred-dollar limit; you use it for something small and predictable like a phone bill and pay it in full every month. After six to twelve months a credit file exists. Check before applying whether the issuer reports to all three bureaus — some report to only one, which is close to useless.
A credit-builder loan is offered by many credit unions. The bank lends you a small sum into a locked savings account, you repay it in instalments, and the repayments are reported. At the end you get the money.
Rent reporting. Several services will report your rent payments to the bureaus for a fee. Useful if you pay rent reliably and have nothing else on file.
Note that a credit file keyed to an ITIN works, but it is thinner than one keyed to an SSN, and if you later obtain an SSN you should ask the bureaus to merge the histories rather than starting again.
Sending money home from the account
Once you have an account, the cost of remittances falls sharply. A wire from a branch is usually the most expensive option. Transfer services that debit a US account directly and pay out in local currency are generally cheaper, and the real cost sits in the exchange rate margin rather than the advertised fee, so compare the amount that actually arrives rather than the fee quoted.
For regular transfers to the same recipient, it is worth setting up a recurring transfer, which many services price lower than one-off sends.
Business accounts, which follow different rules
If you are opening an account for a business rather than for yourself, the analysis changes.
A US business entity — an LLC or a corporation — needs an Employer Identification Number from the IRS. Non-residents can obtain an EIN without an SSN, by filing Form SS-4, and there is a specific process for applicants with no US taxpayer identification number.
With an EIN and the entity's formation documents, a business account becomes possible. But banks apply beneficial ownership rules, which means they must identify and verify the individuals who own or control the entity, and those individuals are then subject to identification requirements of their own. A non-resident owner will be identified under the same non-US person provisions described above, so a passport remains the key document.
In practice, business accounts for non-resident-owned entities are harder than personal accounts, not easier. Many banks require an in-person visit by a controlling person. Some will not open them at all. Specialist providers exist for this market and are worth investigating, but check carefully whether they are banks or programmes running on a partner bank's licence, because the deposit protection and the dispute processes differ.
Joint accounts and family
A joint account with a spouse or partner who has an SSN is often the path of least resistance, because the bank can run its usual process on one holder and apply the non-US person provisions to the other. It is not a loophole; it is simply an easier file for the bank to open.
Think about the legal consequences before doing it. A joint account is generally owned by both holders, with each able to withdraw the whole balance, and it can be exposed to either holder's creditors. For couples that is often fine. For an arrangement with a friend or a more distant relative, it rarely is.
Accounts for children generally require the adult to be identified in the usual way, with the child's identity evidenced through a birth certificate or passport.
What this guide deliberately does not tell you
There is no reliable published figure for the share of immigrants who are unbanked at any given moment, and the numbers that circulate are usually several years old or drawn from surveys with small samples. There is no official list of which banks accept passports, because no regulator maintains one and bank policies change quietly. And nobody publishes an average time to open an account, because it varies from twenty minutes to several weeks depending entirely on which door you walk through.
What is fixed, and what you can rely on, is the regulation. A non-US person may be identified by passport number and country of issuance. Everything else is a bank's own choice, which means it is negotiable, and which means the answer changes if you ask somewhere else.
Frequently asked questions
Do I need to be a US citizen to open a bank account? No. The Customer Identification Program rule explicitly contemplates non-US persons and sets out the identifiers that may be used for them.
Do I need an SSN? Not as a matter of federal law if you are a non-US person. Individual banks may require one as a matter of policy.
Can I open an account before I arrive in the United States? Sometimes. A few international banks offer this to existing customers as part of relocation packages. Most US banks require you to be present.
Will opening an account affect my immigration case? Opening a bank account is an ordinary financial act, not an immigration one. If you have concerns specific to your case, that is a question for an immigration attorney rather than a bank.
Is an ITIN the same as a work permit? No. An ITIN is issued by the IRS for tax purposes only. It confers no immigration status and no right to work.
Can I get a debit card without an SSN? Yes — a debit card is attached to your own deposit account and does not require a credit check.
What if the account is frozen or closed later? Ask in writing for the reason and the specific policy relied on. Accounts are sometimes closed during periodic reviews when documents have expired; supplying a current passport often resolves it.
