@sun @ageha Yeah but ...
I have my excuses!
In order to denounce a citizenship, I must produce a document from the federal tax inspection that I don't have any unpaid taxes. But they aren't giving me one because I left so long ago that there were no computerized records back then, and my former local office misplaced my file in one of the moves.
Also I have to pay $2,500 fee, which is a small price to pay for freedom TBH
