I don't really like the concept of "guests" being applied to people living somewhere for years, working, paying taxes, making families and friends, sending children to school and so on. I think it would be more humane if this concept was minimized, and instead the concept of "no taxation without representation" was applied. Fast track people as much as possible. Maybe one year as a voiceless "guest" is okay for a human being, but not more than that.
