After completion of the JLAB 12 GeV Upgrade Project, the CLAS12 will be only facility foreseen worldwide, which will be capable to obtain electrocouplings of most excited proton states at highest photon virtualities ever achieved in the N* studies from 5.0 to 14 GeV^2. Dedicated experiment on N* studies at high photon virtualities with the CLAS12 detector is scheduled for the beam time in 2015. The area of photon virtualities 5.0<Q^2<14 GeV^2 correspond to the new regime in N* electroexcitation, where the N* structure dominate by dressed quarks, while the contributions from meson-baryon dressiong become negligible. The studies of N* electrocoupling at these distance scales will allow us to answer the key questions of contemporary hadron physics: i) how >98% of N* masses generated non-prerturbatively via dynamical chiral symmetry breaking; ii) how confinement and dynamical chiral symmetry breaking in baryon sector emerge from QCD.
