CONCERNING AMERICANS BORN ABROAD
There are certain elaborations and modifications of the two great principles mentioned above, serving both to confirm and circumscribe them. Children born abroad of American citizens in the foreign service of the United States government are citizens of the United States, and like citizenship comes by birth to children “born out of the limits and jurisdiction, whose fathers were or may be at the time of their birth citizens thereof.”[21] But the father must have been a citizen at the time of the birth of the child, and must have resided actually in the United States; that is, it will not do for him merely to have acquired citizenship abroad by the fact of the citizenship of his father without ever having resided in this country.
If the father loses his citizenship after the birth of the child, it has been held that such child upon attaining his majority may revive his right to citizenship by establishing residence here. And by virtue of legislation enacted in 1907, these foreign-born children of American parentage are required, upon reaching the age of eighteen, to register their intention to become residents, and to remain citizens, of the United States, and upon attaining majority to take the Oath of Allegiance to the United States.
The Department of State has been very liberal in interpreting this provision, allowing the declaration of intention to be made at any time after the person concerned has reached the age of eighteen, and before he has taken the oath, which may be at any reasonable time after his majority. The main question raised is that of good faith. Arises here the principle of “election of nationality”; many countries accord to a person thus in danger of what might be called “dual nationality” the right to choose. This is the case in France, Spain, Belgium, Greece, Italy, Portugal, Mexico, Chile, and Costa Rica. In Portugal, Italy, and France, failure to exercise this choice operates as a choice of citizenship there; in Spain, on the other hand, silence is construed as a choice of the foreign nationality. This is the purport of the American practice.[22]
CHILDREN BORN AT SEA
It is commonly believed that children of foreign parents born on the high seas under the American flag are as a matter of law “born in the United States and subject to the jurisdiction thereof,” but this is not clearly the case. As Borchard puts it, the child “is probably an American citizen under our law and may also be a foreign subject jure sanguinis.” Hence he would, upon attaining majority, have a right of election.
QUESTION OF DUAL NATIONALITY
Can a person gain a new citizenship without losing the old? The aspirant for American citizenship is required in both his declaration of intention and his final petition for naturalization to abjure in most specific fashion not merely all other allegiances, but most particularly that from which he has come. But the sovereignty thus repudiated is not always willing to be abjured, and international diplomacy has been in the past much occupied with the tangles growing out of the question of “dual nationality.” For one not uncommon example, the child of alien parents born in the United States and thereby under our law a citizen of this country, may be taken in childhood back to his father’s native land, and upon reaching military age may be summoned to military service. The United States has not been prone to defend such persons when their actual residence in the old country was clear, but it has been maintained that upon the attainment of his majority such a person has the right to elect and re-establish his American citizenship.
The most common difficulties arise practically, however, from the fact that under the terms of his declaration to become a citizen of the United States, the alien repudiates his allegiance to his fatherland and its sovereignty, but does not gain, and cannot gain, for at least two years in any circumstances, a new citizenship. He has in most specific fashion flouted the government he had, but the government he desires to have will not protect him. For his practical uses, it is a question whether he has now two nationalities or none! Moreover, there have been countries and times in which the right to change allegiance was altogether denied.
In their attitude on the subject of voluntary expatriation the nations differ widely, and are divisible in this matter under three heads: those which deny the right altogether, those which permit it under certain conditions, and those which place no bar in the way.
