We have employed HQET to give the spin-parity quantum numbers for recently observed bottom strange states $B_{ sJ}(6063)$ and $B_{ sJ}(6114)$ by LHCb collaborations. By exploring flavour independent parameters $ \Delta_{ F}^{ (c)} =\Delta_{ F}^{ (b)}$ and $ \lambda_{ F}^{ (c)} = \lambda_{ F}^{ (b)}$, we calculated masses of experimentally missing bottom strange meson states $2S, 1P, 1D$. We have also analyzed these bottom strange masses by taking ${ 1/m_Q}$ corrections which lead modifications of parameter terms as $ \Delta_{ F}^{ (b)} =\Delta_{ F}^{ (c)} + \delta\Delta_F$ and $ \lambda_{ F}^{ (b)} = \lambda_{ F}^{ (c)}\delta\lambda_F$. Further, we have analyzed their two-body decays, couplings, and branching ratios via the emission of light pseudoscalar mesons. Based on predicted masses and decay widths, we tentatively identified the states $B_{ sJ}(6063)$ as $2^3S_1$ and $B_{ sJ}(6114)$ as $1^3D_1$. Our predictions provide crucial information for future experimental studies.
