Nationality Act includes a section and bunch of clauses on how citizenship can be lost. From here.
(6) making in the United States a formal written renunciation of nationality in such form as may be prescribed by, and before such officer as may be designated by, the Attorney General, whenever the United States shall be in a state of war and the Attorney General shall approve such renunciation as not contrary to the interests of national defense;
Is this clause in effect? Who are the officers? Would the person doing this be deported?
