It all depends on the different countries.
If you're talking about Canada specifically, one area of concern for individuals here, particularly for those who have not filed a case, is the length of time. I'm sure you've heard about the issues surrounding legacy claims, as far as individuals who have waited to actually get a hearing.
There is also the issue of access to support. In the Netherlands, for example, when you arrive, you have immediate access to support. In Ontario, if you file a claim, you have to wait up to six weeks to get Ontario Works.
There are some issues as far as access to services when those individuals arrive, and the quality of those services as well.
