When does the premium processing clock start?

What actually starts the clock

The clock starts when the agency receives a properly completed Form I-907 at the correct address - not from the date the petition was filed, and not from the day you posted the envelope. If the form has an error or goes to the wrong place, the clock does not start.

If you add premium processing to a case already sitting in the queue, the window runs from receipt of the I-907, not retroactively from the petition filing. This is a frequent disappointment: people expect the upgrade to 'switch on' the clock from the beginning.

What the window means and what it excludes

The window is counted in business days: weekends and federal holidays do not count. Fifteen business days is about three calendar weeks, and more when holidays fall inside it.

The agency's obligation is to take an action within that window, not to approve. A request for evidence and a notice of intent to deny both count as actions. So an RFE arriving on day fourteen formally means the window was met.

After you answer an RFE the clock restarts - usually a fresh fifteen business days. That is normal behaviour, not a malfunction and not a penalty.

What updates first: the status or the letter

Community members report that the case status in the online account changes first, then the document is generated, and only then does it go out by mail. The gap between the status and the paper notice can be days, sometimes more than a week.

The practical conclusion: go by the status and treat the paper as confirmation. If the status has moved to a decision and no letter has arrived, that is normal. The reverse - the letter arrives while the status has not moved - is rarer and usually means a delayed system update rather than a problem with the case.
