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.
