  We examine the compressed mass spectrum with sub-TeV top squark ($\tilde t$)
as lightest colored (s)particle in natural supersymmetry (SUSY). Such spectra
are searched along with an additional hard jet, not only to boost the soft
decay particles, also to yield enough missing transverse momentum. Several
interesting kinematic variables are proposed to improve the probe performance
for this difficult region, where we concentrate on relatively clean dileptonic
channel of the top squark decaying into lightest neutralino ($\chi_1^0$), which
is also the lightest supersymmetric particle. In this work, we investigate the
merit of these kinematic variables, sensitive to compressed mass region
extending the search by introducing additional states, chargino and slepton
(sneutrino) having masses in between the $\tilde t$ and $\chi_1^0$. Enhanced
production and lack of branching suppression are capable of providing a strong
limit on chargino and slepton/sneutrino mass along with top squark mass. We
perform a detailed collider analysis using simplified SUSY spectrum and found
that with the present LHC data $M_{\tilde t}$ can be excluded up to 710 GeV
right away for $M_{\chi_1^0}$ of 640 GeV for a particular mass gap between
different states.
