The above tables report the number of Labor Condition Applications(LCA) and Labor Certifications(LC) filed by Clean Harbors Environmental Services, Inc. for H1B Visa and employment based Green Card. The data only indicates the number of applications filed by Clean Harbors Environmental Services, Inc.. It does not mean that Clean Harbors Environmental Services, Inc. actually got the visa and hired the workers.

Labor Condition Application(LCA) is different from Labor Certification(LC). LC is for employment based green card while LCA is for H1B visa.

Our LCA data not only includes those filed by Clean Harbors Environmental Services, Inc. for new h1b visa applications, but also those for H1B Visa tranfers and renews. Clean Harbors Environmental Services, Inc. should also file a new Labor Condition Application(LCA) for an H1B Visa petition if the foreign worker changes work location within Clean Harbors Environmental Services, Inc., because the prevailing wage will change. The Immigration and Nationality Act requires that the hiring of a foreign worker will not adversely affect the wages and working conditions of U.S. workers comparably employed.
