It is proved that the moment problem for $K_f$ is solvable provided it is for all sets $K_f\cap C_λ$, where $C_λ=\{x:h_1(x)=λ_1,{...},h_n(x)=λ_n\}$ and $\inf\{h_j(x); x\in K_f\}\leλ_j\le\sup\{h_j(x);x\in K_f\}$. New classes of non-compact closed semi-algebraic sets $K_f$ are found for which the moment problem is solvable.
