Processing time varies by case
USCIS processing time depends on the form, the category you filed under, the office or service center handling it, and the specific facts of your case — and it changes over time. MyCases does not publish averaged processing-day or approval-rate estimates across cases.

Common USCIS statuses for this form
Case Was Received
USCIS has accepted delivery of your filing, logged it, and generated a receipt number beginning with a three-letter service center code. The status confirms that your package and fee were received; it does not mean an officer has read a single page. It also fixes two things that matter later: the received date (which is normally your priority date in preference categories) and the office responsible for the case.
Case Was Approved
USCIS approved the application. This is a decision status and the outcome is favorable, but approval is not the same as having the document in hand: most categories still go through card production, notice mailing, or transfer to another agency, each with its own status. The legally operative item is the written I-797 approval notice that follows; the online status is only a signal that it is coming.
Interview Was Scheduled
USCIS has scheduled an interview and mailed a written notice giving the date, time, location and the documents you must bring. Note carefully that the day this status appears is not the interview date; always rely on the printed notice.
