A laborer's ID card

 

FamilySearch. 1918.

Here's another migration record from FamilySearch, showing the alien agricultural laborer's identification card for Alejandro Portillo. This was used to cross the border at Nogales, Arizona in 1918. The reverse shows this card was stamped by the Salt River Valley Egyptian Cotton Growers Association. This is part of the Arizona Cotton Growers Association, which still exists today.

Another card from the set (see above) shows Alejandro as 52 years old in 1918, which would match the birth year 1866 from the Sonoran records. It isn't clear if Alejandro worked on cotton fields associated with Goodyear Tire and Rubber Company, but this article includes some photos and history on cotton production in the same area where Alejandro could have worked.
