Decay widths of metastable hydrogen atoms subjected to the intense field of the currently available KrF{sup *} laser ({lambda}=248 nm) and ArF{sup *} laser ({lambda}=193 nm) are calculated by solving the full (3+1)-dimensional Schroedinger equation in the space-translated frame of reference. The critical intensities, above which the suppression of ionization decay sets in, are found to be {ital I}{sub {ital c}}{congruent}2.5{times}10{sup 14} and 7{times}10{sup 14} W/cm{sup 2} for {lambda}=248 and 193 nm, respectively.
