Got this from my lawyer
As previously reported, this means that for EB3 applicants from China, India, and the Philippines, their eligibility to file an I-485 application for Adjustment of Status, and the rate at which pending applications in these categories would be approved and issued, would be restricted according to the State Department's priority date system. Each immigrant visa petition has a priority date associated with it (e.g., the date the original application for labor certification was filed, or the date the I-140 petition was filed if no labor certification was required in the category).
The priority date system directly impacts employment based green card applicants in the following ways:
Individuals who have not yet filed their I-485 application for adjustment of status will be eligible to file that application only when their priority date is current (i.e., the priority date is on or before the cutoff date published monthly by the State Department in the Visa Bulletin);
Individuals who have filed their I-485 application for adjustment of status will not have their green cards approved until their priority date is current. However, these adjustment of status applications will continue to be considered to be pending for the purpose of applying for employment authorization documents and advance parole documents;
Individuals with approved I-140 petitions who apply for their immigrant visa through a US consulate in their home country must have a current priority date at the time the immigrant visa application is filed and at the time the application is approved by the consulate.
