As a general rule, the USCIS accepts supporting documents submitted in PDF, and recommendation letters with a digital signature can be accepted when it is possible to verify the authenticity of the document and the identity of the signer. The key point is not the format itself, but the integrity of the evidence.

In the context of an EB-1 petition, letters and supporting declarations are routinely submitted in PDF without issue. For a digital signature, what matters is the assurance that the file was not altered after signing and that the signer is who they claim to be. How each signature is assessed may vary depending on the document and the adjudicating officer.

  • Prefer signatures that allow verification of authenticity and integrity.
  • Keep the original hand-signed document in case it is requested.
  • Check the accepted format in the official instructions before assembling your package.

Since format and signature guidance may be updated, it is worth verifying current requirements directly with the USCIS or with a specialist before submitting your documentation.
