The International Linear Collider is now proposed to begin with a first stage at 250 GeV with an initial integrated luminosity goal of 2 ab−1. I will review the plan for the collider and detectors, the key physics expectations, and recent international discussions. The key physics goal of the ILC250 is precision measurements of the Higgs boson couplings. The exceptional precision of model-independent measurements of all major decay modes makes this program sensitive to possible anomalies due to new physics beyond the Standard Model. Other physics goals will be addressed briefly. The ILC250 infrastructure will support an upgrade future of experiments with e+e− collisions at higher energy up to 1 TeV, building on the success of the first 250 GeV stage.
