The question of whether your government has the will or the ability (the desire) to strictly define boundaries was answered in the spring of 2020. The market test that followed framed a series of restrictions pursued in some locales with militant enthusiasm for a number of years. It did not limit itself by age, race, sex, or origin. There was no shortage of reasoning or justification for any or all of it, no matter how absurd or contrary. So Yes, the government, from top to bottom, is more than able to define constraints and, even under the most ridiculous of circumstances, enforce them.
With that as the foundation, what, then, is the deal with unrestricted immigration?
