This Law Firm Publication by Jackson Lewis P.C. addresses a new Colorado immigration law signed by Governor John Hickenlooper. Since 2007, in addition to the requirement that employers verify the work authorization of all newly hired employees to comply with federal Form I-9 requirements, Colorado has required the completion and retention of an additional affirmation form and the retention of several employee I-9 documents. House Bill 16-114 eliminates these additional verification and retention requirements, effective August 10, 2016. Employers remain subject to the heightened administrative requirements for employees hired until that date.
