Maybe you didn't intend it, but your comment reads like you have an issue with immigrants of certain racial profiles. I'd suggest rewording, unless of course that was your intent behind the comment.

It also comes off as racist/supremacist to term certain countries as "second tier". Unless of course, that is intentional on your part.
