Almost every visa problem I get asked about began months earlier, when somebody picked a category that described their circumstances rather than their intentions. China issues visas against what you will actually do here, and the categories do not overlap politely. Choose wrong and the correction is rarely available from inside the country — you go home, apply again, and come back, a term of school or a start date lighter.

Start with the verb

Five things bring people here. Take the first that genuinely describes your plan, not the one whose paperwork looks easiest.

You will work for a Chinese employer

For most foreign employees the route is an employer-sponsored work permit, a Z visa where one is required, and a work-type residence permit after arrival. It is not the only lawful status under which a foreigner may work — permanent residents need no work permit, and Category A high-level talent enter on an R visa instead — but it is the route almost everyone reading this will take. Your employer applies first, for a Notification of Foreigner’s Work Permit — and in Shenzhen that decision belongs not to a human-resources bureau but to the Science, Technology and Innovation Bureau, which also carries the Shenzhen Foreign Experts Bureau nameplate. Only then can you apply for the visa abroad; the residence permit comes after you arrive. The work route, step by step.

You are joining someone who already lives here

The test is who you are joining, not who you are. A Chinese citizen or a foreigner with Chinese permanent residence puts you in the Q family; a foreigner here on work or study status puts you in the S family. Each splits by length: Q1 and S1 over 180 days, Q2 and S2 for short visits. Bringing family over.

You will study

X1 for a course longer than 180 days, X2 for anything shorter. X1 needs both the admission letter and the JW201 or JW202 form; X2 only the admission notice. Studying here.

You are coming for meetings, a fair or a supplier

The M visa covers commercial and trade activities, supported by documents from your Chinese counterpart or a trade-fair invitation. A stay visa: an extension can be applied for from inside China but is granted at the bureau’s discretion rather than owed, it is never converted into a residence permit, and it is not authorisation to work. Business trips and the M visa.

You are just visiting

The L visa, or possibly nothing at all — China’s unilateral visa-free arrangement lets ordinary passport holders of forty-plus countries enter for up to 30 days, and is announced to run to 31 December 2026. The list of countries is revised periodically and the scheme has an expiry date, so check your nationality against the current official list ↗ before you rely on it. Note also what it is: a stay, not a status, and it cannot become a residence permit. Visiting and visa-free entry.

Talent routes, and the exceptions

Three cases sit outside the five above. None of them is a shortcut around the work permit, and two of them are commonly misdescribed online, so they are worth stating plainly.

The K visa

A category for young science and technology professionals, created by a State Council decree announced on 14 August 2025 and in force from 1 October 2025. Its distinguishing feature is that an application needs no domestic employer and no inviting entity, which is what makes it interesting to people with no offer in hand. Read what it permits carefully: the official release describes exchanges in education, culture and science and technology, together with entrepreneurial and business activities. That is not the same thing as authorisation to take a salaried job with a Chinese employer, and nothing published so far says a K visa replaces the work permit. Implementing detail is still settling and missions are applying it differently, so confirm with the post that will handle your file rather than with anything you read about it — including this. The State Council announcement ↗

The R visa

The entry category for high-level foreign personnel and for skills classed as urgently needed — in practice, people who qualify as Category A under the work-permit classification. It is an entry document, not a work authorisation: an R visa holder who intends to work still needs the work permit and the work-type residence permit, and the advantage is in the processing rather than in skipping a step. Validity and permitted stay per visit are considerably longer than the ordinary categories.

Permanent residents

A foreigner holding Chinese permanent residence does not need a work permit and does not need a visa to enter. This is the case that makes the flat statement “the Z visa is the only lawful way to work” wrong, and it is why the wording above is hedged. It is also rare enough that if it applied to you, you would know.

The categories side by side

Four questions decide everything downstream: who it is for, how long you may stay, whether it converts, and whether you may work.

  • Z — employed by a Chinese employer. Converts to a work-type residence permit, 90 days to five years by law. Work: yes, once you hold both documents.
  • S1 — family of a foreigner living here, over 180 days; spouse, parents, parents-in-law and children under 18 only. Converts to a private-affairs permit. Work: no.
  • S2 — the same, 180 days or less, but a far wider family circle, down to siblings, grandparents and grandchildren. No conversion; an extension can be applied for in China, but it is discretionary rather than owed. Work: no.
  • Q1 — family of a Chinese citizen or of a foreigner with Chinese permanent residence, over 180 days. Converts to a family-reunion permit; the length granted sits inside the statutory 180-day-to-five-year range and is decided at the counter, not something you can read off in advance. Work: no.
  • Q2 — the same relationships, 180 days or less. No conversion; extension is discretionary. Work: no.
  • X1 — study over 180 days. Converts to a study-type permit. Work: only with the school’s approval and the location and duration annotated on the permit.
  • X2 — study of 180 days or less. No conversion. Work: no.
  • M — commercial and trade activities. No conversion; extension is discretionary. Work: no, categorically.
  • L or visa-free — visiting. No conversion. Work: no.

Non-work permits — family reunion, private affairs, study — run from 180 days to five years by law, and one to two years is the common outcome; where inside that range your own lands is decided at the counter. A newer K visa for young science and technology professionals took effect on 1 October 2025 and needs no domestic employer; the implementing detail is still settling and missions are applying it differently, so ask the post that will handle your file and confirm against the official source rather than treating anything you read about it as settled.

Three layers, and why they get confused

Newcomers treat these as one thing with three names. Three documents, three authorities, three separate failure modes.

  • The work permit — the labour-side authorisation, filed online through the national system and free at every stage. It says you may be employed, not that you may be here.
  • The visa — the sticker a Chinese mission abroad puts in your passport, and only that. Officers set validity, entries and permitted stay case by case and publish no fixed figure, so anyone quoting you a guaranteed number is guessing.
  • The residence permit — issued after arrival by the exit–entry administration of the public security bureau, and the document that actually lets you live here. Five types: work, study, journalist, family reunion, private affairs. Only the work type carries work authorisation, which is why a spouse on a private-affairs permit cannot simply start a job.
Good to know

The physical Foreigner’s Work Permit card was retired. A national notice effective 1 December 2024 integrated it with the social security card, so after entry you collect no card — you present the Notification, or an electronic social security card carrying the work-permit information. Some official pages still describe the old step.

How the sequence actually runs

  1. Fix the category

    Decide from your intention, not your convenience. Everything downstream inherits the choice, and changing it later usually means applying again from outside China.

  2. Get the sponsoring document

    Each route has one: the work-permit Notification, an invitation letter with the resident’s passport and residence permit for family, an admission letter and JW form for study, a counterpart’s invitation for business. Foreign marriage, birth and kinship certificates need authenticating or apostilling and translating before you fly — the step that delays families most.

  3. Apply at a Chinese mission abroad

    Missions apply the requirements differently and revise their lists without notice. Work from the checklist published by the post that will handle your file.

  4. Enter, and register your address within 24 hours

    A hotel does this at check-in. In a flat, you register at the police station covering the address. Nothing else can start until it exists.

  5. Convert to a residence permit within 30 days

    Where the visa says one is required, you have 30 days from entry to file in person with the exit–entry administration. The statutory decision period is up to 15 working days; Shenzhen promises less, but its own pages disagree, so plan around the statutory limit.

  6. Diarise the renewal the day you collect it

    Renewals are filed at least 30 days before expiry — where you hold both, the work permit extension first and the residence permit after it, because the residence permit cannot outrun the work permit behind it. There is no weekend service, so a permit expiring on a Sunday has to be dealt with by the Friday.

The obligations nobody exempts you from

Three apply whatever brought you here. Register your address within 24 hours of arriving, and again every time you re-enter the country — a day trip to Hong Kong counts. Meet the 30-day conversion window; it is a statutory deadline, not a service target. And keep your passport current, since a permit cannot outlast the passport it sits in. On money: the work permit is free, and the published residence permit schedule is 400 yuan up to a year, 800 for one to three years, 1,000 for three to five. Treat those as indicative and confirm the figure at the counter — schedules are revised. Anything charged on top is somebody’s service fee, not a government one. The residence permit page covers the filing, the registration guide the 24-hour step.

What getting it wrong costs

Shenzhen publishes its penalties plainly, which I find more useful than any amount of warning. Failing to register your address: a warning and a fine of up to 2,000 yuan. Overstaying: a warning, up to 10,000 yuan, and possible detention. Working without both a work permit and a work-type residence permit: up to 20,000 yuan and detention of up to 15 days, with the employer penalised separately under its own schedule. The penalties come from the Exit and Entry Administration Law, which is amended from time to time — read the current text before you rely on a figure.

So, bluntly: do not work on an M visa, an L visa, a visa-free entry or a dependant’s permit. A student working off campus without the annotation sits in the same statutory category as someone with no permit at all. And arriving as a visitor to switch to work status once you have found a job is not a route, whatever a group chat says.

Check it against the source before you act

Visa rules change, and different missions abroad and different bureaus inside China apply them differently. Everything above is the published position as I read it; where Shenzhen’s own pages contradict each other I have said so rather than picking the tidier number. Confirm your case against the National Immigration Administration ↗, the China Consular Service Network ↗ and the Shenzhen residence permit guides ↗ before you book a flight or resign a job. The Exit and Entry Administration Law ↗ is where the deadlines and penalties come from.

If the part that worries you is sequencing — which document must exist before which, and what happens to your family’s applications when yours slips a fortnight — that is most of what my relocation work is, from around ¥1,500 a day, including coming with you to the appointments.
