Short answer
Five things, in this order. **1) A valid ordinary passport** — official guidance requires nothing more; there is no stated six-month minimum, so the passport simply has to cover your stay. Travel documents, temporary passports and emergency passports are not accepted for visa-free entry. **2) A visa, or the right visa-free basis** — China's unilateral policy covers 50 countries for up to 30 days, and the expiry differs by country: Brunei has no set expiry, Russia runs to 31 December 2027, the other 48 to 31 December 2026. If none of those apply you need a visa, unless you qualify for the 240-hour transit exemption (57 countries, up to 10 days, onward ticket required) or the Hainan 30-day route (61 countries). **3) The arrival card** — file it online free through the National Immigration Administration, or fill in the paper card at the port. **4) Your accommodation address** — hotels register you automatically; staying with friends needs police registration within 24 hours of arrival. **5) The passport you booked with** — Chinese rail tickets are real-name: the passport you bought with is the one you show at the gate.
The passport: valid, and nothing more specific
The rule that catches people out is the one people invent. There is no official six-month requirement. The Exit and Entry Administration Law speaks only of holding a **valid** exit/entry document, and the only official page that addresses passport validity at all — the Chinese Embassy in the UK's visa-free FAQ — says an ordinary passport must be "valid for at least the duration of intended stay in China". If your airline or your onward booking imposes a six-month rule, that is the carrier's rule, not China's.
Two things do disqualify a document. **Travel documents, temporary passports and emergency passports are not accepted for visa-free entry** — the rule is an ordinary passport specifically. And the law does not bar entry to anyone holding no valid exit/entry document, so an expired passport is not a shorter version of this problem.
The visa-free basis, and why the expiry date differs by country
China's unilateral visa-free policy covers 50 countries for stays up to 30 days. The Ministry of Foreign Affairs' consular FAQ, published 21 July 2026, states the expiry three ways: **Brunei has no set expiry, Russia runs to 31 December 2027, and the other 48 countries to 31 December 2026.**
Two further routes exist independently of that list. The **240-hour transit visa-free** policy covers 57 nationalities including Russia, allows stays up to 10 days through 65 designated ports in 24 provinces, and requires confirmed onward tickets. The **Hainan 30-day** policy covers 61 nationalities including Russia but only inside Hainan Province. Under all of them the stay is counted from 00:00 on the day after you enter.
The arrival card, and the 24-hour accommodation registration
The arrival card is an entry-information form, not a visa. Since 20 November 2025 you can file it online, free, before you fly, through the National Immigration Administration's website, its 12367 app, the WeChat and Alipay mini-programmes, or the arrival-card QR code. The paper card is still accepted at the port.
Accommodation registration is the requirement people forget. Under Article 39 of the Exit and Entry Administration Law, **hotels register foreign guests themselves** as part of check-in, but foreigners staying in a private home must — or their host must — register with the public security organs **within 24 hours of arrival**. As of 21 September 2026 that registration can be done online anywhere in China through the NIA website, the 12367 app, or the WeChat and Alipay mini-programmes, and online registration has the same legal effect as doing it at a police station.
The train ticket is bound to the passport you bought it with
China's railway system runs real-name ticketing, and for foreigners the passport is the identity document. China Railway's own English FAQ states that foreign passengers can buy real-name tickets with valid passports, that the e-ticket record stores the identity document used at purchase, and that **the same document must be shown to check in and out of the station and to board the train**.
The practical consequence: buy with the passport you will travel with, and carry that passport at the gate. A booking made on one passport and presented with another will not match, which is the single most common cause of a 12306 verification failure.
