A Hong Kong visa is an official travel authorization required for foreign travellers visiting Hong Kong for tourism, business, work, study, family visits, or transit. Depending on nationality, travellers may require a pre-arrival registration, an eVisa, or a full embassy/immigration application. The visa process typically requires a valid passport, recent photographs, travel itinerary, accommodation proof, financial evidence, and purpose-specific documents. Tourist visas usually allow stays of 14–90 days, while work, study, and dependent visas require additional assessments. Hong Kong maintains a smooth and efficient visa system separate from Mainland China, making proper documentation essential for a quick and successful approval.
