The recent intriguing measurements of $R_{K}$ and $R_{K^*}$ are importanthints of new physics that violates lepton universality. We analyze thesemileptonic decays $b \to s \ell^+ \ell^-$ in the framework of the $B-L$extension of Minimal Supersymmetric Standard Model (MSSM) with Inverse Seesaw(BLSSMIS). A salient feature of this model is that one of the right-handedsneutrino can be light and the neutrino Yukawa couplings are of order one. Weshow that the box diagram mediated by right-handed sneutrino, higgsino-likechargino, and light stop can account simultaneously for both $R_{K}$ and$R_{K^*}$. Therefore, while the MSSM cannot explain the $R_K$ and $R_{K^*}$anomalies, the BLSSMIS can account for them, where a significant lepton flavornon-universality might stem from large neutrino Yukawa couplings.
