(a) Passports defined.
“Passport” as defined in INA 101(a)(30) is not limited to a national passport or to a single document. A passport may consist of two or more documents which, when considered together, fulfill the requirements of a passport, provided that the documentary evidence of permission to enter a foreign country has been issued by a competent authority and clearly meets the requirements of INA 101(a)(30).
(b) Passport requirement.
Except for certain persons in the A, C-3, G, and NATO classifications and persons for whom the passport requirement has been waived pursuant to the provisions of INA 212(d)(4), every applicant for a nonimmigrant visa is required to present a passport, as defined above and in INA 101(a)(30), which is valid for the period required by INA 212(a)(7)(B)(i)(I).
(c) A single passport including more than one person.
The passport requirement for a nonimmigrant visa may be met by the presentation of a passport including more than one person, if such inclusion is authorized under the laws or regulations of the issuing authority and if a photograph of each visa applicant 16 years of age or over has been attached to the passport by the issuing authority.
(d) Applicants for diplomatic visas.
Every applicant for a diplomatic visa must present a diplomatic passport, or the equivalent thereof, having the period of validity required by INA 212(a)(7)(B)(i)(I), unless such requirement has been waived pursuant to the authority contained in INA 212(d)(4) or unless the case falls within the provisions of § 41.21(b).
