He is the author of a book titled Undocumented: Immigration and the Militarization of the US-Mexico Border. 
John Moore has focused on the issue of undocumented immigration to the United States since the early 2000s.
John was able to photograph immigrants during their journey, and to U.S. federal agents tasked with deterring them. Moore has also photographed the entire length of the U.S. southern border, and traveled extensively throughout Central America and Mexico, as well as to many immigrant communities in the United States. 
His work includes rare imagery of Immigration Customs Enforcement raids, mass deportations, and the resulting widespread fear in the immigrant community. For its broad scope and rigorous journalism, Undocumented: Immigration and the Militarization of the United States-Mexico Border serves as a record on the prevailing U.S. domestic topic of immigration and border security.
