Abstract: We prove that a nondegenerate CR structure with signature
$(p,n-p)$

at $0\in \mathbb {R}^{2n+1}$ and with $n$

first integrals $z_{1},\cdots ,z_{n}$ satisfying

$\begin{equation*}dz_{1}\wedge d\bar {z}_{1}\wedge \cdots \wedge dz_{n}\wedge d\bar {z}_{n} \ne 0\end{equation*}$

is realizable if and only if an action of the group $O(2p,2n-2p)$

leaves invariant a one-dimensional subbundle of the structure bundle.
