In this paper we study on stratified dusty viscous fluid through a porous medium past an infinite porous vertical plate in presence of magnetic field with time dependent suction. We consider that the free stream oscillates about a constant mean and suction velocity is exponentially decreasing function of time. The liquid velocity, particle velocity and skin-friction for liquid and dust particles have been investigated. The effect of magnetic field, Grashof number, permeability and stratification factor on velocity profiles and skin-friction have been studied with the help of graphs and tables.
