The controlling period is the one printed on the notice itself, not a general assumption. Responding after it, or not at all, may lead to a request for further evidence being treated as unanswered and to refusal. Submitting something new later does not automatically reset that period.
Sequencing a registry request against an official deadline
If the registry cannot provide the record before the deadline, seek prompt advice on an adequate response, permissible alternatives and any extension actually available. Evidence that you requested a document is not automatically a substitute for the document, and an incomplete response can still result in refusal. Keep submission receipts and follow the agency’s delivery instructions; a later document does not automatically reopen the response period.
Your notice period, your job search and your family's school year run on dates you can name. Keep a simple log: the payment date, each verification you performed, each enquiry and any answer received. Only successful vetting leads to the government’s request for its US$1 million gift. Promotional or general processing language is not an individual guarantee.
