After you land: the 30-day residence permit, visa extensions, and what a port visa does not do

If your plan ends at the airport, you have misunderstood half the system. A Chinese visa authorises entry; it does not by itself authorise the stay that follows, and for several classes it triggers an obligation you must discharge within a fixed number of days. This page covers the two mechanisms that exist after entry, who each one applies to, and the one place you go to use it.

This page only covers what you do in China after you are already inside. Deciding which visa or exemption lets you get in is a different question, covered on the entry decision page.

The 30-day residence permit

The Law of the PRC on the Administration of Exit and Entry of Nationals sets one rule plainly: where a visa states that a residence permit must be applied for after entry, the holder must apply within 30 days of the date of entry, to the exit-entry administration of the local public security bureau at county level or above in the intended place of residence.

Three things in that sentence do the work. The 30 days run from the date of entry, not from when you collect your permit and not from some other administrative milestone. The authority is the public security bureau at county level or above in the intended place of residence, which is the city where you are going to live, not necessarily where you landed. And the application is biometric: the Law requires fingerprints and other biometric identification information to be recorded when you apply.

The Law also sets the validity range of the permits themselves, which tells you how long you are actually covered once you get one: work residence permits run from a minimum of 90 days to a maximum of five years; non-work residence permits run from a minimum of 180 days to a maximum of five years.

Extending a short stay

If your visa says nothing about a residence permit, the mechanism that applies to you is extension of the visa stay itself. The rule is the same Law, Article 29: where a foreign national needs to extend a stay, the application must be made to the exit-entry administration of the local public security bureau at county level or above in the place of stay, before the stay period stated on the visa expires.

Note the direction of that deadline. It is before expiry, not after. An application made after the stay period has run out is a different and much harder problem than an application made in the days before the visa runs out. If you know on the day you land that you need longer, raise it early.

Which visas can actually be extended here

The Law grants the right to apply for extension to foreign nationals whose visa stay is 180 days or less. Within that, the National Immigration Administration gives a practical answer to which specific classes are handled locally, and it is narrower than the Law on its face.

That table is the answer to the most common version of this question. The eligible population is foreign nationals in China for short-term non-diplomatic, non-official activities, such as business cooperation, visits and exchanges, investment and entrepreneurship, visiting relatives, tourism and private matters, who have a legitimate and reasonable reason to continue staying. The eligible classes are the four above. Note that the L class appears for extension but not for renewal or re-issuance: a tourist visa can be extended, but not renewed.

What a port visa does and does not give you

A port visa, the visa some countries call a visa on arrival, is frequently assumed to be a lighter-weight normal visa, useful for a longer visit. The official position is that port visas are a way or method of applying for a visa, not a category of visa. That framing matters after you arrive, because the port visa is issued as one of the ordinary short-stay classes, and what follows an ordinary short-stay class is exactly what the two sections above describe.

So if you entered on a port visa, your ability to remain longer runs through the extension mechanism, subject to the same class list, M, F, S2 and Q2 for extension, renewal and re-issuance, L for extension only, and to the same ceiling that total extensions may not exceed the period originally annotated. A port visa does not create a separate, more permissive stay regime.

Two practical points from the official port visa guidance are worth carrying forward. First, a port visa is issued for entry at the port where you applied for it; the official guidance is explicit that once issued, you enter China from the port at which you applied. Second, if your port visa is lost or damaged after you have entered, the Law gives you a route: apply to the exit-entry administration at county level or above in your place of stay for a renewal or re-issuance, under the same category rules as above.

The registration obligation, and the extension you already hold

Two further obligations sit alongside these, and both come from the same Law rather than from local practice.

• Accommodation registration. If you stay in a hotel, the hotel registers you under the hotel-industry public security rules and reports the foreign guest registration information to the local public security organ. If you stay anywhere other than a hotel, you or your host must register with the local public security organ within 24 hours of moving in. This obligation exists regardless of your visa class.
• Extending a residence permit you already hold. If you are residing in China, the application to extend the residence period must be made to the exit-entry administration at county level or above in your place of residence before the permit expires, thirty days before expiry. That is a materially earlier deadline than the seven days that applies to extending a short visa stay. Where the extension is not granted, you must leave on time.

Two decisions that are final, and one deadline you should not miss

The Law makes certain refusals final decisions rather than first-instance ones that can be reconsidered. A refusal to extend, renew or re-issue an ordinary visa, a refusal to handle a foreigner stay or residence permit, and a refusal to extend a residence period are all final. The Law does not provide for an internal reconsideration of these decisions.

Which makes the timing of the application the part that is genuinely yours to get right. Nothing in the process allows a final refusal to be reopened because the applicant had a good reason for asking later. Two deadlines, 30 days for the residence permit and 30 days before expiry to extend a residence permit already held, are the ones to put in your calendar before you land, not after you have decided you need them.

What this page cannot tell you is whether your specific application will be approved. The Law provides that where an extension is not granted the authority need not give reasons, and the same finality applies to refusals. Confirm the current procedure, the materials and the processing arrangements directly with the exit-entry administration of the public security bureau in the place where you will be staying, and against the official pages linked below.
