  QCD radiative correction to Higgs $\rightarrow$ two photons decay rate is
calculated. Below the threshold we found negligible correction, thus supporting
results obtained earlier by Djouadi et all [7]. Above the threshold radiative
correction appears to be large for both real and imaginary part of H $\gamma
\gamma$ vertex. This leads to radiative correction for $\Gamma $(H $\rightarrow
\gamma \gamma $) to be of order 20--100 percents at $m_{t}=150 GeV$.
  Possible applications of our results for Higgs search at Next Linear
Colliders (NLC) are briefly discussed.
