Providing citizenship to all unauthorized immigrant workers in the United States would add at least $1.5 trillion to the American economy and $367 billion in federal and state tax revenue over the next decade, according to a new UCLA study. By comparison, granting citizenship only to the members of that group who are considered “essential workers” — including in agriculture, retail and construction — would generate an additional $1.2 trillion to the nation’s gross domestic product and $298 billion in tax revenue over the same time frame. Granting citizenship only to people covered by the Deferred Action for Childhood Arrivals policy, or DACA, would generate $112 billion in GDP and $28 billion in tax revenue; and granting citizenship only to recipients of Temporary Protected Status would account for $62 billion in GDP and $16 billion in tax revenue. The study’s publication comes as Congress and the Biden administration are considering ways to move forward on immigration reform. In the past two months, multiple standalone bills have been introduced to address specific aspects of immigration policy. Some proposals would grant citizenship to certain groups of unauthorized immigrants — those covered by DACA or Temporary Protected Status, for example — while excluding others. The report’s authors note that excluding certain groups of immigrants from earning citizenship would mean forgoing billions of dollars in economic output and tax revenue, and the potential for creating tens of thousands of jobs. The study is a collaboration among the UCLA Latino Policy and Politics Initiative, the UCLA North American Integration and Development Center and the UCLA Institute for Research on Labor and Employment.
