The estimates of the economic gains of an inclusive immigration reform we present here are conservative and focus on the regularization of immigrant workers who currently reside in the United States; however, the U.S. Citizenship Act of 2021 and other legislative proposals would also provide a path for increased legal immigration, which would also improve economic efficiency and result in higher GDP growth, tax revenues, job creation, and international remittances. Therefore, a more complete estimate of the economic impact of the U.S. Citizenship Act would account for increased legal immigration. This increased immigration could produce additional GDP gains of $957 billion over 10 years (assuming the arrival of 700,000 authorized immigrants per year). Remittances to Mexico and Central America are estimated to produce a total flow of $1.2 trillion, resulting in increased U.S. exports to the region as well as increased savings which can be used to address root causes of outmigration as called for in the U.S. Citizenship Act of 2021. However, we do not address remittances or projected flows of new migration in this brief.
