We present a fully correlated ab-initio calculation of electronic states of H- in a strong electromagnetic field, in the high-frequency limit. We find a nonmonotonic increase of the detachment energy with increasing field intensity, to a value larger than that of the unperturbed H- ion. Several light-induced bound states do appear, among which doubly excited states. Curves giving the binding energies of these states as a function of intensity are presented.
