For those that want an outline of how it might actually play out, rather than the more fanciful “Trump can do whatever he wants and nobody can stop him” argument, I found this article from Mother Jones informative:
Basically, it would start with an executive order that would declare that there was an “invasion” and that children of the “invaders” should not be given passports, Social Security cards, or other documents that prove citizenship. It would also declare a more restrictive interpretation of the 14th Amendment and the Kim Ark case.
I would imagine rather quickly some baby would be denied documentation and the case would be taken up by the ACLU. I would also expect that the executive order is likely to be stayed until a final ruling is made by SCOTUS, but I suppose it’s possible that a lower court might allow it to remain in force until that final ruling.
Whether SCOTUS would ultimately allow a President to unilaterally declare some arbitrary group of people “invaders”, and thus remove the protections of the 14th amendment, is (amazingly) anybody’s guess at this point.
But I imagine it would not be a blanket “nobody gets citizenship at birth anymore” EO, but rather one that says “no children born after Feb 1, 2025 to parents who are foreign invaders from the following countries (Mexico, Venezuela, Ecuador, etc) shall be issued citizenship-affirming documents because this administration does not consider them “subject to the jurisdiction” of the United State as required by the 14th amendment”.
There are also some practical enforcement issues, in that I’m not sure that the federal government can require a state to verify and list parental immigration status on birth certificates. So it’s not entirely clear to me how the State Department (for example) would be able to deny a passport to a baby born in California (for example, if they don’t go along with verifying parental citizenship) without adding additional paperwork requirements that don’t currently exist to all passport applications.
Right now the primary way to prove your citizenship for a passport is:
I guess you could add the requirement to verify parental citizenship or place of birth, but that could be a very big challenge for many folks, even “real Americans”. Maybe they will decide it’s worth it to stop the “invaders”. I suppose the time-gated nature of it would limit the impact, since it would only apply to kids born after a certain date and most parents have proof of their own citizenship (which would still just be a birth certificate) they could submit with a passport application for their child.
