Thien Le is an immigrant from Vietnam and expectant mother living in California on an H-4 visa. Le has sued the Trump administration in an attempt to block President Trump's Executive Order 14160, which denies birthright citizenship to children born in the U.S. whose parents are not citizens or lawful permanent residents. The plaintiff argued that this order directly violates the 14th Amendment, which establishes birthright citizenship, and should to be declared unconstitutional.
