China has 1.4 million immigrants, and 12000 foreigners with permanent residency. Not per year, but total, cumulative [1]. Despite having 4x the population of the USA.
Meanwhile the USA has gone from 83% White in 1970 [2], to White children being a minority [3] in less than 50 years. And most of that change was due to legal immigration (that they were promised wouldn't change anything [4]) Yet still they're called out for not erasing their own identity even faster.
So do you just not believe in the national right to self-determination, to decide who may live among them? Do you also not believe in this right for Kashmir [5,6] or Palestine?

[6] Human rights activists said that the moves to change Kashmir’s status were only the first steps in a broader plan to erode Kashmir’s core rights and seed the area with non-Kashmiris, altering the demographics and eventually destroying its character. Previous laws barred outsiders from owning property. - https://www.nytimes.com/2019/08/05/world/asia/india-pakistan...
