Each quarter the Department of Labor Office of Foreign Labor Certification publishes statistics on the number of Prevailing Wage Determinations (PWD) filed with its office. Included in this publication are the number of PWDs filed, the number processed, the top employers who have filed a PWD, the occupations for which a PWD is sought, the top H-1B employers who have filed and the top H-1B occupations for which the PWD is filed. The number of PWD requests for any given quarter of a fiscal year can be a good indicator of the number of PERM applications that will be filed in that fiscal year. This number will have significant impact on future priority date movement or retrogression of visa number availability. See below.
