The upload documents process should be completed only after the traveler has confirmed nationality, purpose and stay length. Cape Verde separates short-stay pre-registration from consular visa approval.
A careful upload documents workflow reduces errors in passport number, flight date, accommodation address and payment proof, which are the details most likely to create airline or border questions.
Use printed and offline copies after completing upload documents because airline desks and immigration counters may need to verify evidence quickly.
Practical planning note
For cape verde upload documents, the strongest file is the one that tells the same story across passport data, flight dates, accommodation, payment proof and the declared purpose of travel.
