The Higgs-mediated flavor violating bottom-strange quarks transitions induced at the one-loop level by a nondiagonal Hbs coupling are studied within the context of an effective Yukawa sector that comprises SU{sub L}(2)xU{sub Y}(1)-invariant operators of up to dimension six. The most recent experimental result on B{yields}X{sub s{gamma}} with hard photons is employed to constrain the Hbs vertex, which is used to estimate the branching ratio for the B{sub s{yields}{gamma}{gamma}} decay. It is found that the B{sub s{yields}{gamma}{gamma}} decay can reach a branching ratio of the order of 4x10{sup -8}, which is 2 orders of magnitude smaller than the current experimental limit.
