The successful run of ICARUS-T600 at LNGS underground laboratory, receiving CNGS beam and atmospheric neutrinos, represents the first large-scale example of a liquid Argon TPC in a neutrino physics experiment. The relevant physics and technological results proved the maturity of the LAr-TPC technique. Updated results on the search for LSND-like ve appearance in CNGS beam neutrinos are presented.The ICARUS-T600 detector will take part in the SBN project at the Booster beam at FNAL, that has the goal to provide a definitive answer to the sterile neutrino puzzle by measuring both ve appearance and Vμ, disapperance. The detector is currently undergoing an extensive overhauling at CERN, involving especially the development of a new light detection system; installation at FNAL is scheduled for the beginning of 2017.
