Trump's Birthright Citizenship Order Will Test The Supreme Court

In the Trump administration’s telling, however, everyone’s been getting it all wrong for the last 150 years. “The Fourteenth Amendment has always excluded from birthright citizenship persons who were born in the United States but not ‘subject to the jurisdiction thereof,’” the order stated. “Consistent with this understanding, the Congress has further specified through legislation that ‘a person born in the United States, and subject to the jurisdiction thereof’ is a national and citizen of the United States at birth.” Accordingly, it laid out additional categories of American-born citizens whom it hopes to exclude.

The first and most important thing to note about the order is that it is not retroactive. Nobody currently living in the United States is affected by it at this moment, no matter their parentage or lawful presence. Instead, it says that it “shall apply only to persons who are born within the United States after 30 days from the date of this order.” In other words, the first children affected by it will be born on or after February 19.

From there, the order says it applies to any child whose mother “was unlawfully present in the United States” or “whose mother’s presence in the United States was lawful but temporary,” so long as the father is also neither a U.S. citizen nor someone with lawful permanent status. In other words, a child born to at least one parent with lawful permanent residence or U.S. citizenship would be unaffected by its restrictions. (The emphasis on the mother’s presence may be meant for cases where a father is not listed on birth records.)
