why than doesn't the dominican government enact laws to regulate haitian immigration, these messures could and should include better control at the border?
if there is one lesson on illegal immigration that applies world wide, it is the fact that you can't control your borders, it is simply not possible.
if the dominican government were able to shut down the border completely, pressure would rise in haiti, worsening the situation, and leading to another crisis, which would affect the dominican republic too, as every major crisis in haiti does.
the dominican government does not have the resources to solve haitis internal problems and effectively reduce poverty there.
