The USCIS (Department of Homeland Security) has revised the I-9 form which must be used by all businesses to record the status of ALL new hires (not just foreign nationals). This form, which has now been published, must be used for any required purposes starting January 22, 2017, though prior forms can be used up until that date.
Failure to use and maintain this form can subject a business to substantial penalties, even if done in good faith, and there are strict guidelines as to when it must be completed, starting immediately at the moment of hiring, and completed before 3 days have elapsed.
In addition, the form must reflect expiration of work authorization for those who are not US citizens or permanent residents, and must be updated on the basis of any expiring permit.
IBLF can conduct an I-9 audit of any business which needs to ascertain if they are complying with the law, and to provide recommendations for proper implementation by your human resources department.
