Yes.

Initially, in June 1862, residents of New Orleans were given the option of taking an Oath of Allegiance to the United States, or if claiming foreign citizenship, an oath of neutrality. Passage of the Federal Confiscation Act and its signing by President Lincoln on 17 JUL 1862 opened the door to the seizure of property of "disloyal" residents. General Butler added this to his program in September 1862.

See Department of the Gulf General Orders No. 76 dated 24 SEP 1862 (OR, I, Volume XV, pp575-6), General Orders No. 82 dated 17 OCT 1862 (OR, I, Volume XV, p581), and memo from Brigadier General T. W. Sherman, commanding the Defenses of New Orleans, to Lieutenant Colonel Irwin, Assistant Adjutant General, Department of the Gulf dated 28 MAR 1863 (OR, I, Volume XV, p696).

Thanks Hugh, this is the information I needed. My soldier was injured at Shiloh, discharged, and sent home to New Orleans for the duration of the war. I presumed he and his wife would have had to take an oath--but I don't know where to look for it. No mention of it in his service records.
