USCIS reminds the public that the use of the new Form I-9 became mandatory on January 22, 2017. This means that every Form I-9 completed on or after that date must be done on the new form. The new Form I-9 can be obtained online at https://www.uscis.gov/i-9. At the same time, USCIS issued a revised version of its Handbook for Employers that guides employers through the Form I-9 provisions. This handbook is available at https://www.uscis.gov/i-9-central/about-form-i-9.
