Canada

So you think someone should somehow just get citizenship just because they’ve stayed there for long enough? Many countries do not approve of dual citizenship, and so most people would have to give up on their original citizenship to become a Canadian citizen. That’s not something to be taken lightly of. People have relationships in their home country, and they might lose easy access to their home country by forfeiting their citizenship and getting a Canadian one. How they get taxed in their original country also changes, and might also be detrimental to their finances depending on how much business and investment they’re conducting. What about having to take care of family?

And even if they don’t have any of those, you may live in a foreign country for 25 years, but you might not have thought of the new country as home, and that could be the case for various reasons, some of which may be bad ones, but there are good reasons as well.

So, like the other comment said, you’re showing a great lack of empathy, but tbf, you might not be aware of these considerations someone has to think about while deciding whether getting that citizenship is worth it.
