Airport Transit Permission and an Entry Visa should not be treated as the same unless the relevant official instructions expressly confirm that they are interchangeable. The cited Hong Kong Immigration Department wording does not establish that equivalence.
What the official wording says
Hong Kong Immigration Department describes its visit/transit page as covering the “entry arrangement for persons who require a visa/entry permit to visit/transit the Hong Kong Special Administrative Region (HKSAR).”
That statement is significant for two reasons. First, it connects visa or entry-permit arrangements with both visiting and transiting the HKSAR. Second, it does not define “Airport Transit Permission,” identify it as an Entry Visa, or state that the two names refer to one permission.
Accordingly, the source supports checking the applicable travel-permission category, but it does not support assuming that the terms are synonyms.
How to check the correct term
Before travel, the reader should review the official instructions for the specific journey. The key questions are whether the wording is “Airport Transit Permission,” “Entry Visa,” “visa,” or “entry permit”, and whether the stated permission applies to airport transit, entry, or a visit.
Similar labels should not be substituted for one another without confirmation. A reference to a visa or entry permit for transit does not, by itself, prove that an Airport Transit Permission is an Entry Visa.
What still needs confirmation
The quoted official wording does not provide a case-specific answer about the equivalence, validity, or travel conditions of either term. Those points remain dependent on the route, the traveller’s circumstances, and the official requirements applicable to the journey. The reader should therefore confirm the exact document or permission required before departure.
