"In these situations, refugees are allowed, and even encouraged, to move across the entire host country and even within regional blocs. This freedom strengthens their match with the needs of the destination societies because they can access more opportunities. It also lessens pressures on host communities because refugees are more evenly spread across the entire population."
Interestingly, the given report supports the decisions made by Texan governor Greg Abbott to send busloads of immigrants to NYC. While the sheer number immigrants defeats the purpose of distributing migrants across the country, it does accomplish its purpose of mitigating some of the pressure present on border cities/states.
Some could argue that the extreme measures Abbott has taken are a function of poor federal oversight in distributing migrants across the U.S. and instead letting them accumulate in border cities, draining resources.
