crown. All friendly resident aliens incurred all the obligations of subjects (The Angelique (1801) 3 Ch Rob App 7). An alien, coming into a colony, also became, temporarily, a subject of the crown, and acquired rights both within and beyond the colony, and these latter rights could not be affected by the laws of that colony (Routledge v Low (1868) LR 3 HL 100; 37 LJ Ch 454; 18 LT 874; 16 WR 1081, HL; Reid v Maxwell (1886) 2 TLR 790; Falcon v Famous Players Film Co [1926] 2 KB 474). A resident alien owed allegiance even when the protection of the crown was withdrawn owing to the occupation of an enemy, because the absence of the crown's protection was temporary and involuntary (de Jager v Attorney-General of Natal [1907] AC 326). Legal allegiance was due when an alien took an oath of allegiance required for a particular office under the crown. By the Naturalisation Act 1870, it was made possible for British subjects to renounce their nationality and allegiance, and the ways in which that nationality is lost were defined. So British subjects voluntarily naturalized in a foreign state are deemed aliens from the time of such naturalization, unless, in the case of persons naturalized before the passing of the act, they had declared their desire to remain British subjects within two years from the passing of the act. Persons who, from having been born within British territory, are British subjects, but who, at birth, came under the law of any foreign state or of subjects of such state, and, also, persons who, though born abroad, are British subjects by reason of parentage, may, by declarations of alienage, get rid of British nationality. Emigration to an uncivilized country left British nationality unaffected: indeed the right claimed by all states to follow with their authority their subjects so emigrating was one of the usual and recognized means of colonial expansion. United States The doctrine that no man can cast off his native allegiance without the consent of his sovereign was early abandoned in the United States, and Chief Justice John Rutledge also declared in Talbot v. Janson, "a man may, at the same time, enjoy the rights of citizenship under two governments." On July 27, 1868, the day before the Fourteenth Amendment was adopted, U.S. Congress declared in the preamble of the Expatriation Act that "the right of expatriation
