8 C.F.R. § 1287.6 : Aliens and Nationality — EXECUTIVE OFFICE FOR IMMIGRATION REVIEW, DEPARTMENT OF JUSTICE — IMMIGRATION REGULATIONS — FIELD OFFICERS; POWERS AND DUTIES — Proof of official records

(a) Domestic. In any proceeding under this chapter, an official record or entry therein, when admissible for any purpose, shall be evidenced by an official publication thereof, or by a copy attested by the official having legal custody of the record or by an authorized deputy.
(b) Foreign: Countries not Signatories to Convention.
(1) In any proceeding under this chapter, an official record or entry therein, when admissible for any purpose, shall be evidenced by an official publication thereof, or by a copy attested by an officer so authorized. This attested copy in turn may but need not be certified by any authorized foreign officer both as to the genuineness of the signature of the attesting officer and as to his/her official position. The signature and official position of this certifying foreign officer may then likewise be certified by any other foreign officer so authorized, thereby creating a chain of certificates.
(2) The attested copy, with the additional foreign certificates if any, must be certified by an officer in the Foreign Service of the United States, stationed in the foreign country where the record is kept. This officer must certify the genuineness of the signature and the official position either of (i) the attesting officer; or (ii) any foreign officer whose certification of genuineness of signature and official position relates directly to the attestation or is in a chain of certificates of genuineness of signature and official position relating to the attestation.
(c) Foreign: Countries Signatory to Convention Abolishing the Requirement of Legislation for Foreign Public Document.
(1) In any proceeding under this chapter, a public document or entry therein, when admissible for any purpose, may be evidenced by an official publication, or by a copy properly certified under the Convention. To be properly certified, the copy must be accompanied by a certificate in the form dictated by the Convention. This certificate must be signed by a foreign officer so authorized by the signatory country, and it must certify (i) the authenticity of the signature of the person signing the document; (ii) the capacity in which that person acted, and (iii) where appropriate, the identity of the seal or stamp which the document bears.
(2) No certification is needed from an officer in the Foreign Service of public documents.
(3) In accordance with the Convention, the following are deemed to be public documents:
(i) Documents emanating from an authority or an official connected with the courts of tribunals of the state, including those emanating from a public prosecutor, a clerk of a court or a process server;
(ii) Administrative documents;
(iii) Notarial acts; and
(iv) Official certificates which are placed on documents signed by persons in their private capacity, such as official certificates recording the registration of a document or the fact that it was in existence on a certain date, and official and notarial authentication of signatures.
(4) In accordance with the Convention, the following are deemed not to be public documents, and thus are subject to the more stringent requirements of § 1287.6 (b) above:
(i) Documents executed by diplomatic or consular agents; and
(ii) Administrative documents dealing directly with commercial or customs operations.
(d) Canada. In any proceedings under this chapter, an official record or entry therein, issued by a Canadian governmental entity within the geographical boundaries of Canada, when admissible for any purpose, shall be evidenced by a certified copy of the original record attested by the official having legal custody of the record or by an authorized deputy.
