If my I-485 application has been pending because of retrogression or quota backlogs, will USCIS request any updated information or documents?

If you are the principal applicant and your employment-based I-485 application has been pending because of retrogression or quota backlogs, the U.S. Citizenship and Immigration Services (USCIS) may request for your updated verification of employment at the time the I-485 application is adjudicated, when your priority date becomes current.
