Certificates of coverage are the forms that the Social Security Administration (in
            case of U.S. certificates) and the Sociálna Poisovòa (in case of Slovak certificates)
            issue to workers who would otherwise have to pay social security taxes to both countries
            on the same earnings. The certificate serves as proof that the worker named on the
            certificate is:
         
         
            - 
               
                  • 
                     subject to the social security taxation and coverage laws of the country issuing the
                        certificate; and 
 
 
- 
               
                  • 
                     exempt from such laws on the same earnings in the other country.
