We conduct a randomized controlled trial providing information about the U.S. green card lottery in a representative sample in Senegal in order to contribute to ongoing debates in the migration literature about (a) the extent to which information frictions impede migration decisions, (b) the relationship between migration aspirations and human capital investments, and (c) whether regular and irregular migration aspirations are complements or substitutes. We implemented this experiment in the fall of 2024, with a sample of 2200 subjects across 144 Senegalese communities, about half of whom were randomly selected to receive detailed information about legal requirements and application procedures for the lottery-based U.S. Diversity Visa Program. Legal requirements include in particular an intermediate level of prior investment in education. We assess the impact of this intervention on expressed migration aspirations, and ask whether it heightened educational and training aspirations for participants and their children. We also test an argument frequently brought up in policy debates, namely that opening up legal migration channels should weaken the demand for irregular migration. This does not appear to hold in our case. In fact, the lottery information broadly increases international migration aspirations, which are in turn a primary determinant of irregular migration intent.
