The ICEP office of each nation evaluates 2 possibly citizens who want to exchange citizenships to determine if they are similar enough demographically. If both nations agree, then the 2 citizens exchange citizenships. An application fee applies, and the citizens must fund their own moving expenses. They must show a job or job offer in their destination country.-- awesomest, Aug 12 2025 hmmm, permanently or for set lengths of time?-- 2 fries shy of a happy meal, Aug 12 2025 High frequency alternating citizenship-- pocmloc, Aug 12 2025 //show a job or job offer// or, in the case of retirees, evidence of similar medical coverage.-- Sgt Teacup, Aug 12 2025 random, halfbakery
