we well know that, a coherent state keeps to be a coherent state in its evolution
does similar conclusion hold for a squeezed state?

the answer is YES!
i have make out of it
Doesn't a coherent state stays coherent under the evolution of a Hamiltonian that is at most quadratic in Position and momentum. If I am thinking correctly, if a non-quadratic appears in the Hamiltonian the coherent form of the state is no longer valid under time evolution.
I am pretty sure the same thing is true for squeezed states as well.
