China S2 Medical Visa Guide 2026
How Foreigners Get Medical Treatment in China – Step by Step
Last updated: July 2026
Quick answer: If you need medical treatment in China lasting more than 30 days, you need an S2 visa (private affairs visa for medical purposes). The key document is a hospital invitation letter issued by a licensed Chinese hospital. The entire process takes about 2–4 weeks from start to finish.
Do You Actually Need a Visa?
Citizens of 77+ countries (UK, Canada, Australia, most of the EU, Japan, South Korea, and many others) can enter China visa-free for up to 30 days under the policy extended through December 31, 2026. If your treatment — consultation, screening, minor procedure — fits within 30 days, you don't need any visa at all.
| Scenario | Visa Needed? | Best Option |
|---|
| Health screening, consultation, minor procedure (≤30 days) | ❌ No | 30-day visa-free entry |
| Complex treatment, multi-stage therapy, inpatient rehab (>30 days) | ✅ Yes | S2 medical visa |
| Emergency / unplanned care | ⚠️ Case by case | Port visa or extend after entry |
What Is an S2 Visa?
The S2 visa is a short-term private affairs visa (up to 180 days) for foreigners entering China for personal matters — including medical treatment. It is the correct visa category for planned medical care in China.
- Duration: Up to 180 days, matching your treatment plan
- Entry: Single or double entry (typically single)
- Extension: Possible at local PSB exit-entry bureau if treatment continues (usually +30–180 days)
- Not for: Work, study, or long-term residence
Step-by-Step Application Process
1 Get a Hospital Invitation Letter
This is the most important document in your application. A licensed Chinese hospital must issue an invitation letter on official letterhead with a hospital stamp.
What the letter must include:
- Hospital letterhead + official stamp (chop)
- Patient's full name and passport number
- Medical diagnosis
- Proposed treatment plan and estimated duration
- Treating department and hospital contact details
- Attending physician's signature
How to get it:
- Send your medical records and diagnosis to the chosen Chinese hospital's international medical department
- Hospital reviews your case (typically 3–7 working days)
- Hospital confirms they can treat you and issues the invitation letter
- You receive a scanned copy (sufficient for visa application)
Which hospitals issue invitation letters?
Most top-tier (Grade 3A) public hospitals with international medical departments — Ruijin Hospital (Shanghai), Peking Union Medical College Hospital (Beijing), Huashan Hospital (Shanghai), and many others. Some hospitals work with medical tourism facilitators like MedTourChina.
2 Complete the COVA Online Application
Since September 30, 2025, all China visa applications are processed through the COVA (China Online Visa Application) system.
- Go to consular.mfa.gov.cn/VISA/
- Register an account (email required)
- Select the Chinese embassy/consulate covering your place of residence
- Choose visa type: S2
- Fill in personal and passport details
- Upload supporting documents (see below)
- Submit and wait for preliminary review (1–2 working days)
Documents to upload:
| Document | Details |
|---|
| Valid passport | At least 6 months validity, 2+ blank pages |
| Passport photo | 33×48mm, white background, recent |
| Hospital invitation letter | The key document from Step 1 |
| Proof of financial means | Bank statements, sponsor letter, or insurance covering treatment costs |
| Flight itinerary (optional) | Can provide after visa approval for some consulates |
| Accommodation proof | Hotel booking or host's invitation |
3 Submit Passport In Person
Once the online review is approved, your application status changes to "Ready for Submission". You then:
- Print the barcode confirmation page
- Visit the Chinese embassy/visa application centre in person (or send a representative)
- Submit your original passport
- Pay the visa fee
| Service | Processing Time | Fee (approx.) |
|---|
| Standard | 4–5 working days | $140–185 USD |
| Expedited | 2–3 working days | +$20–30 |
| Rush | 1 working day | +$30–40 |
Note: Fingerprinting is not required for S2 visa applicants at most consulates. A friend or family member can submit and collect your passport on your behalf.
4 Collect Your Visa & Enter China
- Return to the embassy/centre to collect your passport (with S2 visa inside)
- Check the visa sticker carefully — name, passport number, dates, duration of stay
- Book your flight to China
- Upon arrival, complete temporary residence registration within 24 hours (hotels do this automatically)
Important: After entering China on an S2 visa, you must register your accommodation with the local police station within 24 hours. Hotels handle this for you; if staying at a private residence, you or your host must visit the local police station.
Already in China (Visa-Free)? Here's How to Switch
You cannot convert a visa-free stay into an S2 visa from inside mainland China. But many people use this workaround:
- Enter China visa-free (up to 30 days)
- Visit the hospital, confirm the treatment plan, and obtain the invitation letter
- Fly to Hong Kong (visa-free for most nationalities)
- Apply for an S2 visa at the Office of the Commissioner of the Ministry of Foreign Affairs in Hong Kong
- Processing takes 3–5 working days
- Return to mainland China with the S2 visa (fresh 180-day stay)
Why Hong Kong? Most nationalities enter visa-free, the Chinese foreign ministry office processes S2 visas quickly (3–5 days), and you can return to mainland China the same day you collect your visa. Other options include applying at Chinese embassies in nearby countries like Thailand or South Korea.
Can You Extend an S2 Visa?
Yes, if your treatment lasts longer than expected. Before your authorized stay expires, visit the local Exit-Entry Administration Bureau (公安局出入境管理局) with:
- A letter from your hospital confirming ongoing treatment needs
- Your passport
- Completed extension application form
- Temporary residence registration slip
Extensions are typically granted in 30–180 day increments. Each extension costs around ¥160–200 RMB.
Visa Costs Summary
| Item | Cost |
|---|
| Visa application fee (standard) | $140–185 USD (varies by nationality) |
| Expedited processing | +$20–40 USD |
| Hospital invitation letter | Usually free (some hospitals charge a small admin fee, ¥200–500 RMB) |

Quick Checklist
- Confirm your treatment exceeds 30 days — if not, use visa-free entry
- Contact a Chinese hospital and obtain an invitation letter
- Complete the COVA online application (consular.mfa.gov.cn/VISA/)
- Upload all documents and submit for review
- Visit the Chinese embassy/consulate with your passport
- Pay the fee and wait 4–5 working days
- Collect visa, check details, and book your flight
- Enter China and register accommodation within 24 hours
Pro tip: If your treatment is straightforward and can be completed in under 30 days, you may not need a visa at all. Check if your nationality qualifies for China's 30-day visa-free policy before starting the S2 application process.
Frequently Asked Questions
Can I work on an S2 visa?
No. The S2 visa is for private affairs (medical treatment) only. Working is strictly prohibited and can result in fines, detention, and deportation.
Can I bring my family?
Family members can apply for their own S2 visa as "accompanying family" or use the visa-free policy (up to 30 days) if they meet the requirements.
Is travel health insurance required?
Not mandatory for the visa application, but strongly recommended. Medical evacuation insurance is especially important for major procedures.
Can I apply from a country where I'm not a resident?
Generally no. You should apply at the Chinese embassy/consulate covering your country of legal residence. Some people apply in Hong Kong or nearby countries, but rules have tightened.
What if my visa is rejected?
Rejections are rare if you have a valid hospital invitation letter and sufficient funds. Common reasons: incomplete documents, mismatch between passport and application, or previous immigration violations. You can reapply after addressing the issue.
