The DOL has issued notification of Prevailing Wage Determination Request process changes. Certain nonimmigrant (H-1B, H-2B, E-3, etc.) and permanent immigration proceedings (PERM) mandate prevailing wage research. Effective Jan. 1, 2010, the Office of Foreign Labor Certification (OFLC) National Prevailing Wage and Helpdesk Center in Washington, DC will adjudicate all prevailing wage determination (PWD) requests. At least initially, all PWDs will need to be submitted via mail. Consequently, the timing of their filing will need to be planned accordingly in order to correspond with time sensitivity of the underlying immigration proceedings.
