It is far better of a deal as an American to get EU citizenship in any EU country. This confers you Freedom of Movement Rights to live/work/retire in any EU or EFTA country, once you acquire the EU citizenship. You will always be seen as “the American” and also so with your American credentials. For Americans, usually the best country to do this is Republic of Ireland, as a it permits dual citizenship and it only takes 5 years to become a citizen.
With Irish citizenship, you also get Freedom of Movement rights to live/work/retire in the UK, unlike other EU passports due to old treaties and ties with the British.
Also, many people on here could work without having to get sponsorship in Ireland as they have the qualifications to get a skills waiver from the Irish government.
Once you are an Irish citizen, you will legally have the rights to work remote-based US-only jobs anywhere in the Ireland, the UK, EU, and EFTA. You just have your US employer hire you on as a contractor and have an Irish payroll company take care of the US (global income taxation) and Irish (residence based income) taxes. Obviously you forfeit Irish workers rights going this and you are subject to US employment law in this case, generally speaking.
