In this paper, we investigate nonlinear boundary problems for difference equations with causal operators. Our boundary condition is given by a nonlinear function, and more general than ones given before. By using the method of upper and lower solutions coupled with the monotone iterative technique, criteria on the existence of extremal solutions are obtained, an example is also presented.
