The short answer
Four documents sit behind the phrase “China work visa,” and they are not interchangeable:
| Document | Issued by | When | What it authorizes | Validity |
|---|---|---|---|---|
| Foreign Work Permit Notification | Science and technology / foreign expert bureau | Before travel | The right to apply for a Z visa | 3 months (long-term work) |
| Z visa | Chinese embassy or visa center abroad | Before travel | Entry for employment purposes only | Usually single entry, 30-day stay |
| Foreign Work Permit | Same bureau, after entry | Within 15 days of entry | The employment relationship | Tied to the contract and employer |
| Work-type residence permit | Public security exit-entry administration | Within 30 days of entry | Legal stay in China | 1–5 years, tied to the employer |
The Z visa is a ticket to the airport, not a permission to work. The work permit is the permission to work. The residence permit is the permission to stay. All three are needed, in that order.
Why the Z visa alone is not enough
Article 41 of the Exit-Entry Administration Law is explicit: foreigners working in China must obtain a work permit and a work-type residence permit, and no entity or individual may employ a foreigner who lacks them.
The Z visa is issued on the strength of the notification, but it is categorized as a visa, not a permit. It lets the holder enter and gives a short window — normally 30 days — to complete the domestic formalities. During that window, the person is legally present but not yet legally employed. Starting work on day one after landing, before the work permit and residence permit are issued, is technically illegal employment.
In practice, many employers allow a new hire to “start onboarding” immediately. That is a compliance risk, not a convenience. The safe position is that work begins when the work permit and residence permit are in hand, or when the local authority has confirmed in writing that the person may start while the residence permit is pending.
The 2024 change: the permit moved into the social security card
Since December 1, 2024, China has been integrating the Foreign Work Permit into the electronic social security card. New applicants receive an electronic record rather than a separate card, and the permit information is verified through the card. Existing physical permits remain valid under a no-change, no-replacement principle and are converted at the next renewal or change.
This changed the format, not the legal structure. The employer still files the permit application, the foreign expert bureau still approves it, and the residence permit still comes from the exit-entry administration. What changed is the evidence: when applying for the residence permit, the applicant may present the work permit notification or the electronic social security card containing the permit information, without first collecting a physical work permit card.
For employers, the practical effect is that there is less paper to collect and more reliance on the online record. Keep the system screenshots and approval notices; they are now the audit trail.
The residence permit is tied to the employer
The work-type residence permit is not a generic visa. It is issued for a specific purpose and a specific employer. The National Immigration Administration’s guide lists the work permit and an employer certification letter as the supporting documents, and the permit’s validity is set by the applicant’s category: up to five years for high-end talent, urgently needed professionals, and investors; up to two years for employees of reputable registered entities; up to one year for others.
That employer link has three consequences:
- Changing jobs requires a new filing. The old employer cancels the work permit, the new employer files a new one, and the residence permit is updated. The old permit does not travel with you.
- The permit expires with the employment relationship. If the contract ends and the permit is canceled, the residence permit is no longer supported. A short stay visa or a new application is needed to remain lawfully.
- The employer’s compliance history matters. A company with tax, labor, or foreign-affairs violations can have its filings refused, which strands the employee even if the employee’s own documents are perfect.
Where the R visa and K visa fit
The Z visa is the standard employment entry visa, but it is not the only category that can lead to a work permit.
- R visa. For high-level or urgently needed talent. It is tied to Class A recognition and can offer a longer stay and faster processing. The work permit and residence permit are still required after entry; the R visa changes the entry route, not the domestic authorization.
- K visa. Introduced on October 1, 2025 for young STEM talent. It does not require a Chinese employer or inviter at application, and it permits education, research, cultural exchange, entrepreneurship, and business activities. It does not authorize employment. A K visa holder who takes a job still needs a work permit and a work-type residence permit.
The common thread is that no entry visa substitutes for the domestic work authorization. The visa category determines how you enter; the work permit and residence permit determine whether you may work and stay.
Three scenarios that go wrong
Scenario one: the employee starts before the residence permit. The Z visa is in the passport, the work permit has been filed, and the residence permit appointment is two weeks away. The employer asks the employee to begin. If an inspection occurs, the employee is working without a work-type residence permit. The fix is to wait, or to obtain written confirmation from the local exit-entry administration that work may begin during processing.
Scenario two: the employee changes employers and keeps working. The old employer agrees to a friendly departure and does not cancel the permit immediately. The employee starts at the new company on the old permit. This is illegal employment by both parties, because the permit names the old employer. The correct sequence is cancellation, then a new application within 30 days, then work.
Scenario three: the employee works on an M or F visa. A business visa is for meetings, trade, and non-commercial exchanges. It does not authorize employment, including “trial” work, unpaid work, or work paid offshore. If the activity looks like employment, the visa category is wrong.
What the penalties look like
Article 80 sets the floor and ceiling:
- Foreigner working illegally: fine of RMB 5,000 to RMB 20,000; serious cases may add detention of 5 to 15 days.
- Employer: RMB 10,000 per illegally employed foreigner, capped at RMB 100,000, plus confiscation of illegal gains.
- Job introducer: RMB 5,000 per illegally introduced job, capped at RMB 50,000 for individuals and RMB 100,000 for entities.
The financial penalty is rarely the largest cost. Detention, deportation, a re-entry ban, and a damaged immigration record affect future visa applications in China and sometimes in other jurisdictions.
How to keep the sequence clean
- Confirm the notification is issued before booking travel.
- Enter on the Z visa and keep the entry date.
- File the work permit within 15 days; do not wait for the residence permit appointment.
- File the residence permit within 30 days.
- Do not start work, change employers, or take on a different role until the permit reflects it.
If you are an employer planning a start date, build in two to three weeks after entry for the domestic filings. If you are an employee, do not resign from a current role or move countries until the notification is in hand.
