Immigrants still revert to native sub-fertility after a generation, or two at most.

Immigration may be a solution for countries in the Anglosphere, as there are countless educated English speakers who want to immigrate.

Countries in the rest of Europe and in East Asia do not have the luxury of educated, native-language speakers in the millions wanting to immigrate. Those who do want to come to us instead of the Anglosphere, either lack marketable skills or lack the language skills necessary to be a part of society. This imposes considerable costs, and our pension systems are not equipped to handle people working here for 20-30 years and then living off a government pension for another 20.
