Your ITIN application was not accepted because the IRS does not accept notarized copies of documents as proof of identity and foreign status. According to the IRS guidelines, only original documents or copies certified by the issuing agency are acceptable. Notarized copies do not meet this requirement.
The IRS requires that the documentation submitted with Form W-7 must be either:
Certified copies must bear an original, authentic stamp or seal placed by the issuing agency. Photocopied seals or stamps are not acceptable and will result in the application being rejected.
For dependents, a passport without a date of entry into the United States will not be accepted as a standalone identification document unless the dependent is from Canada or Mexico or is a dependent of U.S. military personnel stationed overseas. In such cases, additional documentation to prove U.S. residency is required.
To resolve this issue, you should resubmit your ITIN application with either the original passport or a certified copy of the passport from the issuing agency. If you need your original documents for other purposes within 60 days, you may apply in person at an IRS Taxpayer Assistance Center or through a Certifying Acceptance Agent who can verify your documents and return them to you immediately.
