Most living in Bosnia along the Croatian border in the south-west are already ethnic Croatians, and they cross the border unimpeded to Croatia for all its benefits. Those that are not ethnic Croatians are likely ethnic Bosnian there, who cross as unimpeded as well, except they likely give less shit about it because they are just visiting their relatives or enjoying their EUR-bought or built homes during the summer but then go back to Germany to work for the rest of the year.
