Apply for an ITIN from Your Country

The IRS uses one Form W-7 worldwide, but passport certification, translations, international delivery, and treaty questions differ by location. Choose your country for practical guidance while keeping the federal eligibility rules consistent.

These guides explain process and documentation, not individual tax or immigration advice. Always use the current IRS form and instructions when you file.

Before relying on a country guide, confirm that you need an ITIN and cannot obtain an SSN. Read the ITIN guide for foreign nationals and the complete ITIN document requirements.
