Emission line polarization of T Tauri stars provides us unique information on the circumstellar structure and kinematic motion around these objects. However, foreground interstellar polarization of these objects is often crucial to evaluate their intrinsic polarization correctly. We performed estimation of the foreground polarization of five bright T Tauri stars (TTSs), T Tau, RY Tau, RW Aur, SU Aur, and GW Ori, by measuring foreground interstellar polarization of the cautiously selected field stars, which have a close separation angle from the target TTSs (
