Trump wall: New proposal ties Dreamer plan to border wall
The White House has tied any new deal on young undocumented immigrants to a clampdown on illegal immigration, including a border wall with Mexico.
US President Donald Trump is asking for funding for the wall, speedier deportations and the hiring of thousands of new immigration officials.
Last month he ended the Obama-era "Dreamer" programme which had protected some 690,000 immigrants.
Leading Democrats in Congress have rejected the latest proposals.
They accused Mr Trump of backtracking on a commitment not to include the border wall in negotiations over the status of young immigrants, who are mostly from Mexico and other Latin American countries.
The Deferred Action for Childhood Arrivals (Daca) programme, set up in 2012 under President Barack Obama, is due to expire in March, casting doubt on the future of those protected.
"These findings outline reforms that must be included as part of any legislation addressing the status of Deferred Action for Childhood Arrivals recipients," Mr Trump wrote in a letter to Congress accompanying the list.
His legislative affairs director, Marc Short, said the priorities were "essential to mitigate the legal and economic consequences of any grant of status to Daca recipients".
Last month, Mr Trump told Congress, which is dominated by his Republican party, it had six months to agree new legislation to help the Dreamers.
