Young immigrants and supporters walk holding signs during a rally in support of Deferred Action for Childhood Arrivals (DACA) in Los Angeles, California on September 1, 2017. A decision is expected in coming days on whether US President Trump will end the program by his predecessor, former President Obama, on DACA which has protected some 800,000 undocumented immigrants, also known as Dreamers, since 2012. / AFP PHOTO / FREDERIC J.
