(a) Evidence. Generally, an alien who is required to demonstrate his or her physical presence in the United States on a specific date in connection with an application to adjust status to that of an alien lawfully admitted for permanent residence should submit evidence according to this section. In cases where a more specific regulation relating to a particular adjustment of status provision has been issued in the 8 CFR, such regulation is controlling to the extent that it conflicts with this section.

(b) The number of documents. If no one document establishes the alien's physical presence on the required date, he or she may submit several documents establishing his or her physical presence in the United States prior to and after that date.

(c) DHS-issued documentation. An applicant for permanent residence may demonstrate physical presence by submitting DHS-issued (or predecessor agency-issued) documentation such as an arrival-departure form or notice to appear in immigration proceedings.

(d) Government-issued documentation. To demonstrate physical presence on the required date, the alien may submit other government documentation. Other government documentation issued by a Federal, State, or local authority must bear the signature, seal, or other authenticating instrument of such authority (if the document normally bears such instrument), be dated at the time of issuance, and bear a date of issuance not later than the required date. For this purpose, the term Federal, State, or local authority includes any governmental, educational, or administrative function operated by Federal, State, county, or municipal officials. Examples of such other documentation include, but are not limited to:

(e) Copies of records. It shall be the responsibility of the applicant to obtain and submit copies of the records of any other government agency that the applicant desires to be considered in support of his or her application. If the alien is not in possession of such a document or documents, but believes that a copy is already contained in the Service file relating to him or her, he or she may submit a statement as to the name and location of the issuing Federal, State, or local government agency, the type of document and the date on which it was issued.

(f) Other relevant document(s) and evaluation of evidence. The adjudicator will consider any other relevant document(s) as well as evaluate all evidence submitted, on a case-by-case basis. The Service may require an interview when necessary.

(g) Accuracy of documentation. In all cases, any doubts as to the existence, authenticity, veracity, or accuracy of the documentation shall be resolved by the official government record, with records of the Service having precedence over the records of other agencies. Furthermore, determinations as to the weight to be given any particular document or item of evidence shall be solely within the discretion of the adjudicating authority.
