“The executive order doesn’t become effective for 30 days,” DOJ attorney Brad Rosenberg declared of the directive Trump signed Monday, which instructs federal agencies not to accept or create U.S. citizenship documents for children born to those who are unlawfully in the U.S. or who are here on temporary visas, including student and work visas.

Among the 26 executive orders President Donald Trump signed on his first day back in office is an order to end some forms of birthright citizenship.

President Trump's executive order challenging birthright citizenship will face its first legal test in a Seattle courtroom Thursday.
