of course, but I wouldn’t say that the USA is much harder. Having immigrated an ex-wife and her kids in a prior life, I should know. There is no work requirement, unless that’s something new.
that doesn’t really make any sense. Thais have citizenship at birth, not after a lifetime. If someone is living and working here and wants citizenship, and if they’re younger, we can assume they will keep working and contributing for a long time.
