Consular Office ID Policy
A Matricula Consular ID
(also known as Matricula Consular de Alta Seguridad (MCAS), or as a
Consular Registration) is a document that is issued in the Mexican Consulate to Mexican foreign
nationals that reside in the U.S.
The memo states that the MCAS is sufficient to identify the individual and as proof
nationality, but is not sufficient to verify an immigrant’s legal immigration
the U.S. or eligibility for benefits under the Food Stamp Program.
