Encouraging Naturalization: The Broader Effects of DACA on U.S. Immigration

This paper examines how protection from deportation and work authorization affect immigration outcomes, focusing on Deferred Action for Childhood Arrivals (DACA). Using a difference-in-differences design exploiting geographic variation in exposure to DACA-eligible immigrants, we find that DACA significantly increased the number of naturalized citizens without increasing the number of noncitizens. This increase is driven by higher naturalization among prior noncitizens, most of whom are likely not DACA beneficiaries. We provide evidence consistent with DACA increasing incentives for, and reducing barriers to, naturalization by protecting undocumented DACA-eligible contacts, suggesting temporary protections can encourage longer-term commitments and permanent residence among existing immigrants.
