  Studies of semileptonic $B_s$ decays by the Belle, Babar and D0 experiments
are reported. In particular measurements of inclusive semileptonic $B_s$ decays
by Belle and Babar and the exclusive excited charm mode $B_s \to D_{s1} \mu
\nu$ from D0 are presented. An outlook on further semileptonic $B_s$
measurements with $\Upsilon(5S)$ data at Belle and Belle II is also given.
