The Thirty Meter Telescope (TMT) is an extremely large optical-infrared telescope with diffraction-limited performance that will shape the landscape of astronomy for the next 50 years from its vantage point in the northern hemisphere. The TMT International Observatory (TIO) is a public-private-international partnership that unites the scientific, instrumental and industrial communities of India, Canada, China, Japan and the USA for this endeavor with all partners contributing to the design, development, and scientific operation of the observatory. TMT is now part of the US Extremely Large Telescope Program (US-ELTP), in partnership with the Giant Magellan Telescope in the southern hemisphere and NSF’s National Optical-Infrared Astronomy Research Laboratory (NOIRLab). The National Academies’ latest decadal survey report, Pathways to Discovery in Astronomy and Astrophysics for the 2020s, has ranked the US-ELTP as the highest ground-based priority. This paper will describe recent progress
