With Trump’s executive order, and the ACLU’s challenge, the US federal government has waded into a roiling international debate about how best to care for young people experiencing gender-related distress.

Put simply, under Trump’s order, the children of most undocumented immigrants wouldn’t be US citizens, nor would the children of people in the country on student, work, or tourist visas. This is more than a reinterpretation of the 14th Amendment — it’s an attempt to do away with the jus soli principle that undergirds US citizenship.

The Trump administration's policy bars transgender people from being granted passports that match their gender identity.
