This is the main part:

How will USCIS decide whether to issue an EAD valid for one or two years?

USCIS will decide whether to renew an EAD for either a one or two-year validity period based on the most recent Department of State Visa Bulletin available at http://travel.state.gov/visa/frvi/bulletin/bulletin_1360.html. If an applicant’s visa number has retrogressed and is unavailable, USCIS may issue a renewal EAD valid for two years. USCIS will continue to issue the EAD in one-year increments when the Department of State Visa Bulletin shows an employment-based preference category is current as a whole or the applicant’s priority date is current.
