Verify what the charge is, who issued it and whether it matches the current official stage before acting. Urgency alone is not verification.
Check the payment source
Distinguish a professional invoice from a government request and confirm unexpected changes through an independently verified channel. Keep proof of the instruction and payment together. The official programme does use electronic correspondence, but that does not make every message using its name an authorised demand for money.
Establish the legitimate channels once, in writing, and treat everything outside them as unverified. Note which firm invoices you, from which domain, and to which account. Note separately how any payment to the government is described in the current official procedure.
A request matching neither pattern should be checked with a known contact, using details you already hold rather than the ones in the message. Hypothetical example: a company finance team receives an urgent transfer request naming the applicant’s case. Finance has no way to judge it, which is why the rule and the approver must be agreed before such a message arrives.
Under the current description the applicant, and not the government, is the party making the payment; confirm the instructions from the official source before releasing anything, and record who authorised the release.
