Using U(1) Q invariance, the photon eigenstate and the matching gauge coupling constants in models with arbitrary are given. The mass matrix of the neutral gauge bosons is exactly diagonalized, and the photon eigenstate is independent on the symmetry breaking parameters - the VEVs of the Higgs scalars. By obtaining the electromagnetic vertex, the model is embedded naturally into the standard model.
