  Studying the structure of excited nucleon states employing the
electroproduction of exclusive reactions is an important avenue for exploring
the nature of the non-perturbative strong interaction. The electrocouplings of
$N^*$ states in the mass range below 1.8~GeV have been determined from analyses
of CLAS $\pi N$, $\eta N$, and $\pi \pi N$ data. This work has made it clear
that consistent results from independent analyses of several exclusive channels
with different couplings and non-resonant backgrounds but the same $N^*$
electro-excitation amplitudes, is essential to have confidence in the extracted
results. In terms of hadronic coupling, many high-lying $N^*$ states
preferentially decay through the $\pi \pi N$ channel instead of $\pi N$. Data
from the $KY$ channels will therefore be critical to provide an independent
analysis to compare the extracted electrocouplings for the high-lying $N^*$
states against those determined from the $\pi N$ and $\pi \pi N$ channels. A
program to study excited $N^*$ state structure in both non-strange and strange
exclusive electroproduction channels using CLAS12 will measure differential
cross sections and polarization observables to be used as input to extract the
$\gamma_vNN^*$ electrocoupling amplitudes for the most prominent $N^*$ states
in the range of invariant energy $W$ up 3~GeV in the virtually unexplored
domain of momentum transfers $Q^2$ up to 12~GeV$^2$.
