> doesn’t renunciation of US citizenship actually require an act of Congress annually, under which all recent applicants are included? No. At least, none that I've heard of, and https://en.wikipedia.org/wiki/Relinquishment_of_United_States_nationality https://en.wikipedia.org/wiki/Relinquishment_of_United_State... makes no mention of it. There is a quarterly publication of those who have renounced citzenship - https://en.wikipedia.org/wiki/Quarterly_Publication_of_Individuals_Who_Have_Chosen_to_Expatriate https://en.wikipedia.org/wiki/Quarterly_Publication_of_Indiv... . But that appears to have been put into place mostly to try to shame rich people who expatriated, under an invalid idea that most renunciations were from rich people trying to avoid paying US taxes.
