I have a permanent residency I am USA citizen. I am looking at changing my citizenship to get out of USA tax hell. I see on my permanent residency card it list my USA citizenship. Does anyone know or been through the process to change their citizenship and keep your permanent residency. I know this is not the normal but if my income change I will have this opportunity to change citizenship to much more tax friendly country. It has the same Visitor Visa program free 90 day agreement with Brazil. So it's very similar with the same rules for USA visitor visa.
