Rarely should LCs need to request assistance from an FSP. Generally, foreign agencies
            will obtain evidence directly from claimants residing in their respective countries.
            However, if a request must be sent to an FSP, complete a Form SSA-1320-U4 in legible
            block printing if there are no attachments and the request does not exceed one page.
            The Form SSA-1320-U4 must be typewritten in all other instances.
