  In the ``non-decoupling'' region of the Higgs sector in MSSM, the heavier
CP-even Higgs boson (H^0) is Standard-Model-like and close to the charged Higgs
bosons (H^\pm) in mass, while other neutral Higgs bosons (h^0,A^0) are lighter
and near the Z mass. This scenario is consistent with the current Higgs search
limits, although the improved sensitivity for a light charged Higgs boson
search t -> H^+ b may result in certain degree of tension. We demonstrate that
it can pass the stringent flavor constraints, provided there are other light
SUSY particles to contribute in the loop induced processes. In turn, the
non-decoupling Higgs sector implies the existence of light (left-handed) stop,
sbottom and Wino-like gauginos, with mass all below 250 GeV. These light
super-partners can still escape the current SUSY searches at the LHC. Dedicated
searches for soft decay products should be devised for the LHC experiments to
improve the searching sensitivity. The ILC would be able to cover the full
spectrum region. The solutions for the viable SUSY parameters result from
subtle cancellations and are often missed by the generic multiple dimensional
scans, highlighting the importance of theoretical guidance in search for such
special cases.
