What this restriction category covers
Why airlines can deny boarding when required documents cannot be verified. The practical effect depends on the traveler’s passport, destination, origin, transit, travel date, purpose and selected entry point.
Verification sequence

- Check whether the rule applies to nationality, residence, origin, transit or purpose.
- Confirm its effective date, expiry date and exceptions.
- Check airline or carrier implementation.
- Keep a copy of the official notice.
Documents to prepare
- Passport and copies
- Visa, eVisa or authorization where required
- Onward itinerary
- Health documents where applicable

- Official permit or exemption evidence
Common mistakes
Travelers often rely on a general country summary without checking the exact crossing, transit stop, passport type or travel purpose. A rule that applies to land entry may not apply identically at an airport, and an online visa route does not guarantee that all entry points accept it.
