Unchecked Haitian immigration makes it into the top 5 worries of Dominicans for the country. This is the case since the early 2000 at least. Look at the polls done by the Dominican media every few years.I don't think I have met a single solitary Dominican here who is against a wall and stronger immagration enforcement.
Notice though how Dominicans choose Haitian immigration when that is the only choice regarding this problem. When among the choices are Haitian immigration in general and illegal Haitian immigration, Dominicans pick illegal Haitian immigration. What many people aren’t in agreement with is supporting illegal Haitian immigration, not Haitian immigration in general. People have no issues with legal immigrants from Haiti and no one protest that in every naturalization ceremony there are several Haitians becoming Dominican citizens.
