I am re-registering for TPS and applying for TPS EAD for the first time. I got the TPS and I-765 receipt form(I-797) on january 3rd and the online case status shows it is in progress. Is there anyway I could start working without getting the EAD on hand? Will there be complications if I fill out I-9 with my USCIS#, expiration date of the automatic extension June 2018 and Category A12?
