Abstract: This paper examines whether marriage serves as a strategic response to immigration policy uncertainty. We study transitions into marriage among cohabiting binational couples—defined as unions between a U.S. citizen and a noncitizen partner—following the shift in immigration policy expectations during the 2016 U.S. presidential campaign and the subsequent tightening of enforcement in 2017. Using ACS data from 2008 to 2019 and a difference-in-differences design, we compare marriage transitions among binational couples to those of homogeneous citizen couples. Immigration policy uncertainty increased marriage rates among binational couples by approximately 1.5–1.8 percentage points, or about 8-10 percent relative to pre-treatment levels. Event-study estimates show no differential pre-trends and indicate that the response began in 2016, prior to the formal reinstatement of Secure Communities. The effect is concentrated among likely unauthorized immigrants and individuals from targeted nationalities. The findings suggest that marriage functioned as a form of legal and economic insurance in response to heightened deportation risk.
