Vice-Chairman Diaz has been working with a local Miami organization that cares for hundreds of U.S. children whose parents have been deported. On May 19, 2009 the Miami-Dade Board of County Commissioners approved a resolution urging U.S. Congress and President Obama's administration to amend immigration laws and policies to address U.S. children whose parents have been deported. The legislation, which was co-prime sponsored by Commissioner Javier D. Souto and Vice-Chairman Diaz, followed a citizen's presentation on May 5, 2009 by Nora Sandigo, founder and executive director of American Fraternity, an organization that provides social services to immigrant families.

Sandigo explained the plight of more than 400 children she represents who are orphaned when their parents are deported due to immigration policies; she is their legal guardian. During the citizen's presentation, one child testified about losing everything and having to live in a two-room home with nine people, making it hard to concentrate in school and sleep at night.  Meanwhile, another testified that with her mother and baby brother, she had to live in a home with no electricity after her father was deported.

On June 2, 2009, the County Commission approved a resolution sponsored by Vice-Chairman Diaz to allow County employees to contribute the value of their accrued annual and holiday leave, up to a $250,000 cap, to American Fraternity, Inc.

"I urge our state and federal leaders to provide assistance for the health, education, housing, nutrition and general welfare of these children," added Vice-Chairman Diaz.  "The encouragement and support of the Congressional Hispanic Caucus is greatly appreciated and will hopefully push the issue for the President's consideration."
