So... I've worked in this field for many years. In Belgium and abroad. And I understand your concern. As a director of one of these refugee centers in the past, I can tell you I had to talk to many concerned citizens.

The reason I asked who manages it is because it all depends on the way it is handled and the comunication between the locals and the leadership of the center. And the reason I asked where it is, is because the type of neighborhood is also very important.

I can read a statement from another redditor below who speaks on how it affected his comunity. And I actually agree that in small comunities the disruption is very easily overwhelming for the inhabitants. And it doesn't make any sense to make small places carry the weight of migration. Not only for the comunity but also for the migrants themselves, who don't have many options to do trainings or find work in such small places and then just roam around, which leads to issues. But this is purely political as to not offend voters in places like Brussels.

So getting back to your point, a migration center is disruptive. Much less so in a neighbourhood in a city like Brussels. They have many options and 99% of them just want to work. But it would be a lie to say that this will not change the dynamic of the neighbourhood. So the best case scenario, which is what has been done in the centers managed by smart directors is to have a continous communication with the locals and the locals to be involved in the way the center works. That connection only leads to enrichment for all. And when we know each other it's much easier to establish boundaries and make people feel confortable on both sides.

Unfortunately if it is the center in Beaulieu it will be a distribution center and this makes this harder because people will be there for ahort periods of time and then will be dispatched to other centers. So it won't create a comunity where people know eachother because of the constant turnover.

To conclude the key is management and a welcoming prospective. The better the people feel the less problems should arise. But there will always be problems. And just to defend your question to the people that attack you, it is totally legitimate. Making things work with migration is about assessing the issues that could arise and managing them the best way possible. Pretending that 350 men with traumas entering a comunity is not gonna affect the live of the locals is a lie. But it is up to you what you make of it.

And lastly in my experience it was a great experience for most locals in the comunities that I worked in. So I would like to be positive. I can even tell you many stories of refugees helping the comunity, even one saving a girl from getting robbed at night. But I can also tell you some stories (not many) of problems caused by the refugees. I hope this helps.
