Hello Lucky and Simple Man,
I am not sure if this would help but I have a pending AOS process that currently is in "Initial Review". I copied below what it describes about the "Initial Review" step:
During this step, USCIS initiates the background checks of the applicant/petitioner and identifies issues that may need to be addressed either during an interview or by asking the applicant/petitioner to submit additional information or documentation. USCIS reviews applicant's/petitioner's criminal history, determines if there are national security concerns that need to be addressed, and reviews the application/petition for fraud indicators.
If you have filed an I-485, I-589, I-751, N-400, I-90, I-821, I-131, I-130 or I-765, you can expect to receive an appointment notice to appear at an Application Support Center to have your fingerprints and/or biometrics taken. The timing of your appointment is determined by the number of applicants ahead of you that also need a biometric appointment. We try to schedule biometric appointments as quickly as possible and in most cases you will receive your appointment notice within 30 days of submitting your application. We will send your appointment notice approximately 14 days ahead of your scheduled appointment. It is important that you keep this appointment. If absolutely necessary, you can request that your appointment be rescheduled however, please be aware that rescheduling may delay the processing of your application. Please follow the instructions on your appointment notice if you need to reschedule.
