Start with the USCIS received date on your receipt notice. Enter it in the Regular-processing calculator and keep the notice with your application records. Using that same date whenever you revisit the tracker makes successive estimates easy to compare and helps you describe exactly how long the application has been pending.
Create a short event log as official updates arrive. A useful format has three columns: event, date, and source. Add the receipt, any evidence request and response, the decision, card production, and mailing information when available. Keeping each event on its own row preserves a clear history for your school or employer.
At approval, move your attention to the delivery stage. Record the decision date, then follow card-production and mailing updates through your USCIS account. Once a delivery-tracking number is available, use it to follow the shipment. The approval-to-card range in the calculator helps you reserve time for this part of the process.
Place your employer's onboarding deadline and proposed first day next to those milestones. For initial OPT, confirm the authorized start date and required documents with your DSO and employer. This turns a general wait into a concrete plan: which date matters next, which document is needed, and when should you send another update?
