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.
Michigan Senator Jacob Howard insisted upon the addition of the text in bold specifically because he wanted to make it clear that the mere "accident of birth" in the United States was not sufficient to justify citizenship. "[The amendment] will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers accredited to the Government of the United States, but will include every other class of persons."
Despite that addition, the Supreme Court has interpreted the Fourteenth Amendment as granting citizenship to every person born in the United States.
What do you think is the proper interpretation?
This is good. It is ridiculous to be born in a country and not have given citizenship. Like The Mennonites in Mexico did not get their Mexican citizenship until the late 80s... in spite of having been there for a few generations.
