We consider a subcritical branching process with immigration, infinite number of types T1, T2, ... of particles, and discrete time. The state of the process at the moment of time t is the set of vectors

where ξi (t) is the number of particles of type Ti at the moment of time t, i = 1, 2, ... It is assumed that at each moment of time only particles of type T1 immigrate and each particle of type Ti turns into a set of particles of types Ti and Ti + 1. It is proved that the probability distributions of the vectors (r, t ) converge as t → ∞ to discrete limit distributions.
