The Trump administration has formally announced the end of the Deferred Action for Childhood Arrivals (DACA) programme, which had protected nearly 800,000 young undocumented immigrants brought to the US as children from deportation and provided them the right to work legally. US Congress has until March 2018 to pass legislation similar to DACA before some of the young adults who qualified for the programme will become eligible for deportation. Hundreds of business leaders co-signed a letter in advance of the decision calling on the administration to preserve the DACA programme and on US Congress to pass the DREAM Act.
