Hi anoj 123, if your visa status shows approved, that means it is approved and it will show you ready to print, Ready to print means, you have to pay 200 QAR fees and get your visa printed and then your mother in law can come, In Case if your application gets cancelled , you have to apply again, or if it gets rejected, u need to visit immigration office gharafaa, they will let u know the reason for rejection.Thankyou
