Take a look at this excellent piece on the Citizenship Clause of the 14th Amendment. (H/T Legal Theory Blog).

Recently, scholars and lawmakers have suggested that the United States, or even states, cease to recognize citizenship of the American-born children of undocumented aliens. This would seem to be a direct contravention of the text of the Fourteenth Amendment, which begins by saying, “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.” Conservative legal scholars have begun to advance scholarly arguments suggesting that the “subject to the jurisdiction thereof” language was “intended” by the Framers of the Amendment to require legal status and “full allegiance” to the United States to activate the citizenship guarantee. A review of the legislative debates during the framing of the Amendment reveals little evidence to support this contention. It indicates that the language was designed to exclude two and only two groups: (1) children of diplomats accredited to the United States and (2) members of Indian tribes who maintained quasi-sovereign status under federal Indian law as it existed in 1868. The contrary contention arises out of a partial and strained reading of the debates and an at best partial understanding of the intellectual background of the Amendment. That proponents of a narrower view propound their interpretation as embodying the “clear intent” of the Framers seems to contrary to the record as to raise questions about the very meaningfulness of “originalist” arguments in general.

I have ruminated a bit about the citizenship in our early Republic, and how a representative or senator could have been a citizen in 1788 at the time of the First Congress. Was the First Congress unconstitutional? This article may have some insights into notions of citizenship in the minds of our framers.
