  Hints of lepton flavor universality violation observed in various flavor
ratios such as $R_D$, $R_{D^*}$, $R_{J/\psi}$, $P_\tau^{D^*}$ and $F_L^{D^*}$
in $B\to D^{(*)}\,\ell \, \nu$ and $B_c\to J/\psi \, \ell\, \nu$ charge current
decays have opened new avenues to search for indirect evidences of beyond the
standard model physics. Motivated by these anomalies, we perform a detailed
angular analysis of $B_s\to D_s^*(\to D_s\gamma,\,D_s\pi)\, \ell\, \nu$ decays
that proceed via similar $b \to c\, \ell\, \nu$ quark level transition. We use
the most general effective Hamiltonian for $b\to \,c\, l\nu$ process and give
predictions of several $q^2$ and $\cos\theta$ dependent observables for the
$B_s\to D_s^*(\to D_s\gamma,\,D_s\pi)\, \ell\, \nu$ decays in the standard
model and in the presence of various real and complex new physics couplings.
The results pertaining to this decay are competent to address the anomalies in
the charge current sector.
