The possibility of the interstellar origin of the long-period comets is disscused. We present methods used in our investigation and results of numerical studies of the galactic influence on the interstellar comets. Some cases of the cometary evolution from the interstellar space to the observability region due to the galactic disk and galactic centre perturbations are shown. Simulated initial parameters of potentially observable interstellar comets population are presented.
