1. Choose Your Account Type and Purpose

| Remote investing or FX | Online multi-currency platforms (e.g., Wise, Revolut, Mercury, Payoneer) |
| Residency or second citizenship banking | Bank in the country of residence (may require proof of address or visa) |
2. Pick a Bank or Jurisdiction
Popular countries for U.S. residents to open international accounts include:

- Switzerland – UBS, Credit Suisse (strict KYC and deposit minimums)

Most banks will ask for:
- Valid Passport
- Secondary ID (Driver’s License or utility bill)
- Proof of U.S. Address
- Proof of foreign address (if applicable)
- Source of funds (bank statements, employer letter, etc.)
- Tax ID (SSN or EIN) — especially due to FATCA compliance

5. Understand Compliance and Tax Rules
As a U.S. citizen or resident, you must comply with:

Failure to report can result in severe penalties.
