  Ginzburg-Landau expansion for superconductors with anisotropic $s-$ and
$d-$wave pairing is derived in the presence of anisotropic normal impurity
scattering which makes $d-$pairing state more stable under disordering. It is
demonstrated that the slope of the upper critical field $|dH_{c2}/dT|_{T_{c}}$
in superconductors with $d-$wave pairing has nonlinear dependence on disorder,
i.e. for the low anisotropic scattering rate it drops rather fast with
concentration of normal impurities, but as anisotropy of scattering increases
it features initial nonlinear growth, approaches a maximum and drops again,
vanishing at the critical impurity concentration. In superconductors with
anisotropic $s-$wave pairing $|dH_{c2}/dT|_{T_{c}}$ grows, approaching the
known asymptotic behavior, characteristic of usual isotropic case irrespective
to the scattering anisotropy.
