In this paper Dufour, Radiation absorption, Chemical reaction, and viscous dissipation effects on Unsteady Magneto Hydrodynamic free convective Casson fluid flow through a semi-infinite vertical Oscillatory porous plate of time dependent permeability with Hall and Ion-Slip Current in a Rotating System was investigated. The dimensionless governing equations for this investigation are solved analytically by using multiple regular perturbation law. The effects of different parameters on velocity, temperature and concentration fields are shown graphically. With the aid of these, the expression for the skin friction, Nusselt number and Sherwood number profiles was done with the help of tables. It was found that as the Ion-slip parameter increases the Velocity and temperature profiles decreases but the velocity and temperature decrease with increases in Hall current parameter. Dufour effect and thermal radiation increases it leads to increase in both velocity and temperature. However an increase in both chemical reactions, Schmidt number, leads to decreases in concentration.
