If everyone is treated equally, then there is no threat of opposing ethnic groups forming a competing identity in conflict with existing identities. The whole reason that was and continues to be a thing in the U.S. is the widely disparate treatment people receive, based purely on superficial notions of race. So to argue they need to be kept away seems like an admission that they will be treated poorly and unequally; otherwise, there is no reason for conflict.
That is, unfortunately, usually the case. Economic migrants (the vast majority, outside of war zones) and invited or tolerated in either because they provide cheaper labour than the locals, or because they carry some actually new know-how. In the first case they will be treated worse, that is the economic motive being their coming. It the second they may or may not be treated worse, depends on what situation their coming is upsetting. In any case they'll land in a foreign land without the usual networks of family and friendship one can rely on, which also puts them as a disadvantage and more exposed to be exploited.
These are problems that can lead to immigrant communities "defending" by creating ghettos and ethnic "networks". There are ways to defend equal treatment for immigrants but those are hard, they require oversight that actually works, they also require an economy where immigration doesn't particularly disadvantage some groups of the local population thus setting the stage for conflicts. The greater the influx the harder it is to handle these problems adequately.
Of course the proponents of multiculturalism seem to believe that ghettos may even be desirable! The invisible hand will also work for immigration, nothing to worry about... The proponents of integration believe otherwise and usually oppose large influxes, the definition of "large" being up for debate.
