You are eligible for visa free entry
Argentine passport holders can stay in Hong Kong for up to 90 days visa-free. This stay limit applies only to Hong Kong - it runs independently and is not linked to any Schengen or regional shared counter. Each visit resets on its own terms.
Your passport should be valid for the duration of your stay, although a minimum of six months' validity beyond your planned departure date is strongly recommended.
An Argentine passport meeting the validity requirement above, with enough blank pages for entry and exit stamps at Hong Kong border control.
Hong Kong immigration officers expect to see a confirmed ticket showing your departure from the city before your allowed stay ends. A return flight to Argentina or any onward booking works - keep the confirmation accessible on your phone or printed.
A hotel booking confirmation, a short-term rental reservation, or a written invitation from someone hosting you in Hong Kong with their full address is standard and straightforward to present.
You should be able to show you can cover your stay without issue. A recent bank statement or an accessible credit card is the simplest way to handle this if asked at the border.
Travel insurance is not required for visa-free entry, but comprehensive medical coverage is strongly recommended.
Hong Kong operates under its own immigration system, entirely separate from Mainland China. If your trip includes crossing into Shenzhen or anywhere on the Mainland, check whether you need a Chinese visa before you travel - the 90-day Hong Kong entry does not extend across the border.
