The "Partner with Korea Act" proposes to create a new nonimmigrant visa classification specifically for nationals of the Republic of Korea, enabling them to perform services in specialty occupations in the United States. This new E-4 visa category requires an intending employer to file an attestation with the Secretary of Labor, certifying compliance with specific labor conditions. The legislation establishes an annual numerical limitation of 15,000 initial visas for principal applicants from South Korea. Spouses and children of these principal aliens would not be counted against this annual cap. The bill also amends existing immigration law to incorporate this new visa into definitions of specialty occupations and relevant attestation procedures, similar to other high-skilled visa programs.
