@misagh4u -- From pages 2 & 3 of the W-7 instructions referenced above:
"2. You must submit original documents, or certified copies of
these documents from the issuing agency, that support the
information provided on Form W-7. A certified document is one
that the original issuing agency provides and certifies as an
exact copy of the original document and contains an official
stamped seal from the agency. You may be able to request a
certified copy of documents at an embassy or consulate.
However, services may vary between countries, so it’s
recommended that you contact the appropriate consulate or
embassy for specific information."
