Commercial Fishing and Seafood Business Act of 2023 This bill expands a provision that exempts certain H-2B visas (temporary nonagricultural laborers) from the annual cap of 66,000 on such visas. Under this bill, the exemption shall apply to H-2B visas issued for employment (1) on a commercial fishing vessel or shrimp trawler; or (2) in the processing of fish, baitfish, or fishery products. Currently, this exemption only applies to H-2B visas issued for certain employment related to the processing of fish roe.
