This bill, titled the Northern Mariana Islands Labor Stabilization Act , significantly amends the existing labor stabilization program for the Commonwealth of the Northern Mariana Islands (CNMI). Its primary purpose is to extend the program's transition period from December 31, 2029, to at least December 31, 2039, and to establish a framework for potential further extensions based on the CNMI's labor needs. The legislation introduces several key modifications to the program's operation. It mandates that temporary labor certification requirements and procedures, similar to those used in Guam, will apply to the CNMI. Furthermore, the bill adjusts the prevailing wage calculation to be 75 percent of the determined wage or the federal minimum wage, whichever is higher, and changes the wage determination from an annual to a biennial basis. Regarding worker permits, the bill sets an annual numerical cap on permits, not to exceed 15,000, to be established by the Secretary in consultation with the Governor. It also includes a supplemental allocation of 3,000 permits specifically for Construction and Extraction Occupations . Permits for most Commonwealth Only Workers will be valid for one year, but a new provision allows certain long-term workers —those admitted in fiscal year 2015 and two of the subsequent four years—to receive permits valid for three years, renewable for additional three-year periods. A new mechanism is established for the Secretary of Labor , in consultation with other federal agencies and the Governor, to determine the CNMI's labor needs by 2039 and potentially extend the program for successive 10-year periods. The bill also imposes a $150 enforcement fee on employer petitions, with funds directed to the Department of Homeland Security for immigration law enforcement. Additionally, it addresses the status of certain aliens for inadmissibility purposes and redefines "qualified alien" to include those lawfully admitted for long-term residence in the CNMI.
