If set in motion, the order will end the automatic citizenship of children born in the US to non-citizen parents.

The executive order signed by Trump specified that a child born in the USA will be granted citizens if at least one parent must be a US citizen, a legal permanent resident (green card holder), or a member of the US military.

"The Secretary of State, the Attorney General, the Secretary of Homeland Security, and the Commissioner of Social Security shall take all appropriate measures to ensure that the regulations and policies of their respective departments and agencies are consistent with this order, and that no officers, employees, or agents of their respective departments and agencies act, or forbear from acting, in any manner inconsistent with this order," read the White House order.
