A U.S.-based Electron-Ion Collider (EIC) has recently been endorsed by the U.S. National Academies of Sciences, Engineering, and Medicine (NAS). This brings the realization of such a collider another step closer, after its earlier recommendation in the 2015 Long-Range Plan for U.S. nuclear science of the Nuclear Science Advisory Committee ``as the highest priority for new facility construction following the completion of FRIB''. An EIC will be an unprecedented collider that will need to maintain high luminosity (1E33-1E34 cm-2 s-1) over a very wide range of Center-of- Mass energies (~20 GeV to ~100 GeV, upgradable to ~140 GeV), while accommodating highly polarized beams and many different ion species. A multi-laboratory collaboration is presently working on two site-specific EIC designs - eRHIC led by BNL and JLEIC led by Jefferson Lab. The JLEIC design maximally leverages the existing CEBAF capability for production of polarized electron beams, and leverages the innovative figure-8 rings to achieve high luminosity and high values of beam polarization for protons, deuterons and other ions. The present talk will summarize the status of JLEIC Electron Ion Collider design and R&D.
