The "hostile environment" is all about illegal immigration and as such is certainly not about pointlessly complicated paperwork for people who are legal immigrants. It says absolutely everything about the extremist position that some people have reached that you appear to be treating illegal and legal immigration as exactly the same, and then describe a government that tries to enforce its own immigration rules as "far right nationalist". If that's the case then practically every country in the world is "far right nationalist", which would make it a meaningless designation. Exactly what it's become!
