  We investigate the lepton flavor violation in the framework of the MSSM with
right-handed neutrinos taking the large mixing angle MSW solution in the
quasi-degenerate and the inverse-hierarchical neutrino masses. We predict the
branching ratio of $\mu \to e+\gamma$ processes assuming the degenerate
right-handed Majorana neutrino masses. We find that the branching ratio in the
quasi-degenerate neutrino mass spectrum is 100 times smaller than the ones in
the inverse-hierarchical and the hierarchical neutrino spectra. We emphasize
that the magnitude of $U_{e3}$ is one of important ingredients to predict
BR($\mu \to e +\gamma $). The effect of the deviation from the
complete-degenerate right-handed Majorana neutrino masses are also estimated.
