Ask the applicant to submit the original insurance booklet if this is the initial
            claim filed on the worker's record. If it is a subsequent claim, ask the applicant
            to submit a copy of any prior award letter.
         
         If neither the insurance booklet nor the award letter is available, list the names
            and addresses of all the worker's employers in Greece in Part I.2. of the SSA-2490-BK
            (Application for Benefits under a U.S. International Social Security Agreement). If
            the worker was self-employed, list the addresses of each place of business.
