Direct answer: File available evidence and explain what is missing; never invent data. Ask whether later supplementation is accepted.
Who this applies to: Anyone waiting for CU, tax return or employer certificate near expiry.
Practical steps: 1) obtain proof of request from employer/CAF; 2) file contract and available payslips; 3) add a note and expected date; 4) send the certificate when received; 5) keep protocols.
Documents to keep: Request proof, payslips, contract, CU/return when available and office messages.
Verifiable timing and costs: Use the deadline in the office request; certificate/translation costs concern the document.
Exceptions and special cases: If the tax year is not closed, explain it; older evidence is supplementary, not an automatic substitute.
If the procedure stalls: The DSU is not ready: the applicant attaches contract, payslips and CAF receipt, then supplements.
Practical example: For example, if the tax certificate arrives after filing, the applicant keeps the employer request proof and sends it through the stated channel when available.
