Mr. Attorney-General Black,3 in the case of Amthor, a Bavarian, naturalized in the United States, who returned to Bavaria, gave an opinion, in 1857, admitting the right to renounce the citizenship of naturalization and resume that of birth, by an actual and bona fide return with family and property and a change of permanent domicile. Mr. Black said that no mode of renunciation was prescribed; but, as the right was admitted, if the fact and intent coincided and were sufficient to satisfy the Government
of the United States, and Bavaria treated Amthor as a citizen, he could not claim the rights of a citizen of the United States or invoke its protection.
