In follow-on guidance, ICE noted that employers could continue to implement the flexibilities until affected employees undertake non-remote employment on a regular, consistent, or predictable basis, or the extension of the flexibilities related to such requirements is terminated, whichever is earlier.

These flexibilities were first announced in March 2020 and subsequently extended throughout the COVID-19 pandemic. Immigration and Customs Enforcement (ICE) announced today that employers will have 30 days to reach compliance with Form I-9 requirements after the COVID-19 flexibilities sunset on July 31, 2023.
