Documents Needed to Open a U.S. Company as a Foreigner: Complete Requirements Guide (2026)
Quick Answer
A foreigner can open a company in the United States without a visa, without residency, and without a Social Security Number. The core documents are: a valid passport, proof of address, a formation document (Articles of Organization or Certificate of Incorporation), an Operating Agreement or Bylaws, a registered agent in the state, and an IRS EIN. To open a bank account, you’ll usually also be asked for a Certificate of Good Standing and a description of your business. This applies to LLCs and C Corporations. S Corporations are not available to non-residents.

1. What Type of Company Can a Foreigner Open?
Not every structure is open to non-residents. These are the ones that apply:
| Type | Available to non-residents? | Comment |
|---|---|---|
| LLC | ✅ Yes | The most popular. Ideal for services, e-commerce, agencies, and freelancers |
| C Corporation | ✅ Yes | Ideal if you want investors or plan to scale |
| S Corporation | ❌ No | Shareholders must be U.S. citizens or residents |
| Partnership (LP/LLP) | ⚠️ Possible | More complex, with specific tax obligations |
| Sole Proprietorship | ⚠️ Technically | No legal protection. Not recommended |
| Nonprofit 501(c)(3) | ⚠️ Possible | Longer and more demanding process |
If you’re not sure which to choose, the practical rule is: LLC to operate and invoice, C Corp to raise capital.
2. Stage 1: Your Personal Documents
These are the owner’s documents. The service provider, the bank, or both will ask for them.
Valid passport. This is the main identity document for foreigners. Check the expiration date before you start, because a passport that’s about to expire can stall your bank account opening.
International proof of address. A utility bill or a recent bank statement, usually from the last 90 days, showing your name and address. This is the document most often rejected for being out of date or for not matching the rest of your information.
Verifiable contact details. Email, phone number, and in some cases a professional profile or website.
Key point: to form the company you don’t need a visa, residency, or an SSN. This is a very common misconception.
3. Stage 2: Formation Documents
Articles of Organization (LLC) or Certificate of Incorporation (C Corp)
This is the document that legally creates the company. It’s filed with the Secretary of State of the state you choose. It usually includes the company name, address, registered agent, and management structure.
Approximate filing cost: between $50 and $150 depending on the state (Wyoming and Delaware, for example, are around $100). Fees change, so always check the state’s official website.
Operating Agreement (LLC) or Bylaws (C Corp)
This is the internal rulebook: who owns what, how decisions are made, how profits are split. In most states it isn’t required to be filed with the government, but banks ask for it, and it protects you in disputes, even if you’re the only owner.
Registered Agent
This is mandatory. It’s a person or company with a physical address in the state of formation that receives legal and government notices on behalf of your company. If you live outside the U.S., you hire an outside one.
Approximate cost: between $50 and $150 per year.
For a C Corp, also:
- Incorporator action (initial appointment).
- Initial board resolutions.
- Stock ledger and issuance of stock certificates.
- List of directors and officers.
4. Stage 3: Tax Documents
EIN (Employer Identification Number)
This is your company’s tax number with the IRS. You need it to open bank accounts, payment processors, and to file taxes. It’s free and can be obtained without an SSN.
As a foreigner, the process is normally done with Form SS-4 by fax, mail, or phone, since the online application is designed for people with an SSN or ITIN. On the SSN or ITIN line, you indicate that it doesn’t apply (foreign).
Typical mistakes: a company name different from the one registered with the state, an incomplete address, and a poor description of the activity. All three delay or block the application.
EIN Assignment Letter (CP 575 or 147C)
This is the document that confirms your EIN. Banks often ask for it, so keep it both digitally and in print.
What about the ITIN?
It isn’t needed to form the company or to get the EIN. You’ll only need it in specific tax situations, such as certain IRS filings or treaty benefits. Consult a CPA if your case requires it.
5. Stage 4: Documents for the Bank Account
This is where many projects get stuck. Forming the company is the easy step; the bank is the one that scrutinizes. Although it isn’t a legal requirement, opening a separate bank account is key to protecting your personal assets.
What they usually ask for:
- Articles of Organization / Certificate of Incorporation.
- Operating Agreement or Bylaws.
- EIN letter.
- Passport of all beneficial owners (generally those who own 25% or more).
- Proof of address of the owner.
- Certificate of Good Standing, which confirms your company is active and up to date with the state. It usually has a short validity, between 30 and 90 days depending on the institution.
- Business description: what you do, who your customers are, from which countries, and how much you expect to bill per month.
- Active website (many fintechs and payment gateways review it).
- Contracts, invoices, or letters of intent backing your activity, in some cases.
Important: some banks and fintechs ask for translated or apostilled documents, depending on your country of origin and the institution. There is no single rule, so confirm before spending on paperwork. And remember: approval is always at the bank’s discretion. Nobody can guarantee it.

About addresses: distinguish between the registered agent’s address (for legal notices), the mailing address (for example, a mailbox with USPS Form 1583), and your actual operating address. Presenting one as if it were another is a frequent cause of rejection.
6. Stage 5: Annual Maintenance Documents
Opening the company is only the beginning. To keep it active you need:
State annual report. Each state has its own calendar and fee. For reference, Wyoming has a minimum of around $60, Delaware charges an annual tax of $300 for LLCs due June 1, and Florida is around $139. New Mexico doesn’t require an annual report. Always verify current figures.
Registered agent renewal.
IRS filing. If your LLC has a single foreign owner, you normally must file Form 5472 along with a pro forma Form 1120, even if you have no income or owe no taxes. The deadline is April 15, with a possible extension to October 15. Failing to file can carry penalties of $25,000. A C Corp files its own Form 1120.
Organized accounting and bank records, in case the bank, the IRS, or the state asks for backup.

9. BOI: Do I Have to Report Anything to FinCEN?
During 2024 and 2025 this caused a lot of confusion. Today the situation is clearer: in August 2026, FinCEN issued a final rule that permanently eliminates the beneficial ownership reporting obligation for companies formed in the United States. In practice, if you formed your LLC or corporation in a U.S. state, even as a foreigner and sole owner, you normally don’t have to file this report.
The exception is foreign entities that register to do business in the U.S.: those remain subject to reporting for their foreign owners. In addition, the federal relief doesn’t replace state requirements; for example, New York’s LLC transparency law imposes its own disclosure obligations on foreign LLCs registered in that state. If you’ll operate in New York, consult a professional first.
10. The 7 Mistakes That Cause Rejections
- Inconsistent name across the state, the IRS, the bank, and your website.
- Expired proof of address or one in someone else’s name.
- Using the registered agent’s address as your real office without clarifying it.
- Not having an Operating Agreement, even for a single-owner LLC.
- A vague business description (“consulting” or “services” with no detail).
- Not filing Form 5472 and discovering the penalty months later.
- Opening the company in a state without thinking about the bank, the business model, and annual costs.

12. Frequently Asked Questions
Can I open a company in the U.S. without living there?
Yes. You don’t need residency or a visa. You only need to be of legal age and meet the state’s requirements.
Do I need a Social Security Number or ITIN?
Not to form the company or to get the EIN.
How much does it cost to gather all the documents?
As a reference, between $300 and $600 in the first year for a simple LLC, adding up the state fee, registered agent, and EIN. It goes up if you use an all-in-one provider or add bookkeeping.
How long does it take?
Formation can take from a few days to a couple of weeks depending on the state. The EIN, from a few days to several weeks by fax or mail.
Which state is best for me?
It depends on your business. Wyoming and New Mexico often stand out for low costs; Delaware for its reputation with investors; Florida if you operate locally.
Does the company give me residency or a visa?
No. It’s a business structure, not an immigration process.
Do I have to pay taxes in the U.S.?
It depends on whether you have U.S.-source income and on your country of tax residency. Even with no tax owed, there are usually forms to file. Consult a CPA.
Can I open a bank account as a foreigner?
Yes, but it’s at the bank’s discretion. Some institutions require physical presence and others allow a remote process.
