In this paper, we investigate the asymptotic behaviors of the critical branching process with immigration \Zn, n≥ 0\. First we get some estimation for the probability generating function of Zn. Based on it, we get a large deviation for Zn+1/Zn. Lower and upper deviations for Zn are also studied. As a by-product, an upper deviation for max1≤ i≤ n Zi is obtained.
