In 2026, the 24-hour Visa-Free Transit (TWOV) in China is actually a "stay permit" rather than a formal visa, and it is available to travelers of almost all nationalities. To obtain it, you must be transiting through an eligible Chinese international airport to a third country (e.g., London to Beijing to Tokyo). You cannot simply fly from London to Beijing and back to London. Upon arrival, follow the signs for "International Transit" or "24-Hour Transit." You will need to present your passport, a confirmed onward air ticket for a flight departing within 24 hours, and a completed arrival card. If you wish to leave the airport for a hotel or sightseeing, you must apply for a temporary entry permit at the immigration counter. As of late 2025/early 2026, China has streamlined this process by adding more eligible ports (totaling 65) and allowing travelers to fill out entry cards online via a digital portal before arrival. This policy is free of charge and does not require pre-approval at a consulate, making it the most efficient way to handle a short layover.
