I think the definitive comment on my yesterday column about U.S. citizenship is this one:”Dear Mr. Derbyshire—One very important benefit of citizenship vs. LPR [i.e. legal permanent residence — the “green card”] status is that, once you become a citizen, you don’t have to live here anymore. You can go and retire in Guadalajara or some other expat enclave and be relatively free from the Nanny State, from crime, and from the high cost of living.” [Derb] I never thought of that. What use would my bolt-hole in China be, if I didn’t have citizenship? Heck, without citizenship, I might not be able to get my Social Security check mailed to me!
