I just read through the instructions for the new I-9 and saw that fields for an email address and phone number have been added to section one. According to the instructions, the fields are optional. However, the fact that entering this information is optional is not noted on the actual I-9 form. The fields on the I-9 should read: E-mail Address (optional) Telephone Number (optional). I can see where a lot of people will ask if they HAVE to enter an email address.
