  We study polarization squeezing of a pure photon number state which is
obviously polarized but the mere change in the basis of polarization leads to
simultaneous polarization squeezing in all the components of Stokes operator
vector except those falling along or perpendicular to the direction of
polarization state, is observed. We use the most general definition of
polarization squeezing and discuss the experimental feasibility of the result.
We also observe that a squeezing operation like non-degenerate parametric
amplification of the state does not reveal simultaneous squeezing in all Stokes
operator vectors and decreases in this sense.
