  Optical polarimetry is an effective way of probing the environment of
supernova for dust. We acquired linear HST ACS/WFC polarimetry in bands
$F475W$, $F606W$, and $F775W$ of the supernova (SN) 2014J in M82 at six epochs
from $\sim$277 days to $\sim$1181 days after the $B$-band maximum. The
polarization measured at day 277 shows conspicuous deviations from other
epochs. These differences can be attributed to at least $\sim$ 10$^{-6}
M_{\odot}$ of circumstellar dust located at a distance of $\sim5\times10^{17}$
cm from the SN. The scattering dust grains revealed by these observations seem
to be aligned with the dust in the interstellar medium that is responsible for
the large reddening towards the supernova. The presence of this circumstellar
dust sets strong constraints on the progenitor system that led to the explosion
of SN\,2014J; however, it cannot discriminate between single- and
double-degenerate models.
