M87 is a promising candidate to reveal the shadow image of its supermassive black hole at its galactic center. Greenland Telescope (GLT) project is aiming to image the black hole shadow for the first time in human history using submm-VLBI technique together with other submm telescopes all over the world, especially with ALMA, JCMT, and SMA to achieve micro-arcsecond resolution, powerful enough to resolve the black hole shadow. The GLT antenna is the 12-m ALMA North America prototype antenna, and has been retrofitted for the extreme weather. In the past two years, we have successfully deployed the antenna to Thule, Greenland. The submm receivers have been installed on the receiver cabin, and currently the telescope is under a thorough commissioning process. We are targeting to join the Event Horizon Telescope (EHT) observation in coming April, which is to observe M87 with submm telescopes all over the world using submm VLBI technique. In this talk, I will present the current status of GLT.
