: Aliens must present unexpired passports or official documents in the nature of passports issued by the government of the countries to which they owe allegiance, or other travel documents showing their origin and identity, as prescribed by regulations.
: If a foreign embassy cancels the passport of an alien, the alien loses the privilege to enter or remain in the Philippines.
: The automatic loss of the privilege to enter or remain in the country due to passport cancellation obviates the need for deportation proceedings under the Immigration Act, Section 37; or the Administrative Code, Section 69.
: Sections 10 and 15 refer to the presentation of travel documents for admission, and Section 37 pertains to deportation procedures.
: Summary deportations can be executed under the authority of the Administrative Code, Section 69, and the Immigration Act when the alien loses the privilege to remain due to passport cancellation.
: It is a mandatory requirement proving the alien's origin and identity, which determines their legal admission into the country.
: No, cancellation of the passport by the home country means the alien loses the privilege to enter or remain in the Philippines.
