Non-western immigrants in the UAE are essentially enslaved. It is clearly in a camp which is separate from mere "strict immigration laws."

The UAE and the US (as of the last year and a half) don't (just) have strict immigration laws. Instead, they have corrupt and abusive immigration systems which operate outside of national and international laws.

I don’t see why you single out non-western immigrants in the UAE and try to depict this as an outcome of corruption or abuse. Most non-western immigrants are subject to the kafala system, but even if they weren’t, their eligibility for citizenship (or not) would remain the same. After all, citizenship is off the table for even the highly privileged Western expat population that is not subject to the kafala system.

Again, the local laws allow for conferring citizenship on exemplary foreigners, which does happen, and so such countries fit easily into camp 2 by which a country has the right to choose who and who not it wishes to make citizens.
