The ruling left unsettled the question of whether children born to immigrants without full legal status in the United States are entitled to automatic citizenship. So what happens now?

Even if the mothers' immigration statuses were called into question and even if Trump was not married to them at the time of the children's births, all of Trump's children have an American father. Thus, Trump's executive order against birthright citizenship would not affect the statuses of his own children.

The Supreme Court allows Trump's birthright citizenship limits to take effect in 28 states, while legal challenges continue in others.
