I pulled the latest overstay data from the CBP website (2024) and compared it to the list of countries. Some of the countries have high overstay rates (Haiti and Laos >24%), but others don't. Barbados (0.44%) has a lower overstay rate than France (0.48%). Libya (1.59%) has a lower rate than Portugal (1.68%). Some countries with high rates aren't on the list entirely, like Malawi (22.05%). Also, the hypothesis fails a chi square test. It's not that.
