Abstract：We consider the nonlinear Schr\{o}dinger equation $$i\psi_{t}=-\Delta\psi+F(|\psi|^{2})\psi$$ in dimension 3. we prove the existence of wave operators for multi-channel problem with large final state. That is, for given final state $(E^{+},\gamma^{+},\varphi^{+})$, we can find initial data $\varphi_{0}$ such that its corresponding solution $\psi(t)$ is asymptotically give by $$\psi(t)\approx e^{it\Delta}\varphi^{+}+e^{it E^{+}+i\gamma^{+}}\phi(E^{+}).$$
