ProEnglish has been a major part of the "English-as-official-language movement." The group also has opposed comprehensive immigration reform. The chief purpose of the organization at the time of its founding was to defend the Arizona "Official English" ballot initiative, which was adopted in 1988, overturned by the Arizona Supreme Court in 1998, and re-enacted in revised form by Arizona voters in 2006. The group has also supported federal English-only legislation, specifically the English Language Unity Act. In addition to seeking the enactment of laws and policies declaring English to be the official language, ProEnglish "seeks to end bilingual education, repeal federal mandates for the translation of government documents and voting ballots in languages other than English." Among ProEnglish's key priorities is the rescission of Executive Order 13166, an executive order signed by President Bill Clinton which states that any entity that receives federal funds "must provide whatever services it offers in any foreign language spoken by anyone likely to receive those services." ProEnglish also opposes Puerto Rican statehood unless Puerto Rico were to adopt English as its official language.
