A visa is only one part of entry preparation. Travellers should also make sure the passport used for the application is the passport carried on the trip and that the authorization dates match the planned arrival.
Visa permission is only one entry check
A valid visa or exemption deals with immigration permission, but travellers should also carry the passport used for the trip and make sure the authorization dates fit the itinerary.
Do not treat a visa approval as a substitute for the underlying travel document.
Check the border date, not just the flight purchase date
The relevant application date is the intended entry into Benin. Overnight flights and multi-country routes can make that different from the day the journey begins at home.
Benin says that intended entry date becomes the start of eVisa validity.
Keep the trip explainable
Accommodation and onward or return arrangements may be useful travel evidence when entry questions arise.
The clearest preparation is a consistent story across passport, visa, bookings and the actual purpose of the visit.
