FASER, the ForwArd Search ExpeRiment, is the newest experiment at CERN’s Large Hadron Collider (LHC) and it is designed to be complementary to the LHC's ongoing physics program, extending its discovery potential to light and weakly-interacting particles that may be produced at the LHC in the far-forward region. It is uniquely situated around 480 m from the ATLAS detector and will be able to detect the decays of long-lived dark photons or axion-like particles with masses in the MeV to GeV range, which are thought to act as a mediator between the particles that make up ordinary matter and a new dark sector. Such a new particle of a dark sector has attracted growing interest because it can yield dark matter with the correct relic density. FASER was designed, constructed, installed, and commissioned during 2019-2022 and has been taking physics data since the start of LHC Run 3 in July 2022. In the first year of run3, we have already collected data delivered from $\mathrm{40\ fb^{-1}}$ (inverse femtobarns) of proton-proton collisions with a center-of-mass energy of 13.6 TeV. We will present the status of the experiment, including detector design, detector performance, and first physics results of new particle searches from Run 3 data.
