this is normal Alert from https://www.uscis.gov/i-485: Alert: USCIS has prioritized employment-based adjustment of status applications during every step of its processing and adjudication during this fiscal year. We continue to make processing and resource allocation decisions to increase the pace of adjudications and limit the potential for employment-based visa numbers to go unused. If you are applying for a Green Card in an employment-based category and we issued you a Request for Evidence (RFE) for your Form I-693, Report of Medical Examination and Vaccination Record, you should respond as soon as possible so we can finalize a decision on your adjustment application.

reply ASAP TO continue your case

Thank you! @Hope Fully.
