Bye, then. I'm staying.

As a physicist Keith, you will be aware of the practice of drawing the best curve through data. Immigration peaked in 2005, well before the recession, and has been mostly going down ever since.

There are new measures in place that authorise control of immigration. You admit that most immigration comes through ports (air and sea) but not through smuggling. In those ports there are immigration control posts.

I wish you the best of luck as you age wherever you go, and the falling population means that there will be no support for you in your old age.
