The China S2 Medical Visa — a plain-English guide

Short-term medical treatment (≤180 days) uses the S2 visa with "treatment" noted on it. Stays beyond 180 days require an S1 with a residence permit. We advise against a tourist (L) visa for hospitalization or surgery — it causes serious problems with extensions and re-entry. If your condition is minor and can be settled in one quick outpatient visit, a regular tourist visa usually works in practice; for any planned treatment, use the S2. Start 8–12 weeks before your planned treatment.

Plan the visa, then the trip

Start 8–12 weeks before treatment

The hospital invitation letter is the document that unlocks everything. We obtain it, check it against embassy requirements, and prepare your application pack.

Documents

What you need to prepare

🛂 Basic documents

Passport valid for 6+ months beyond your stay, with at least 1 blank page
Visa application form completed on COVAS (consular.mfa.gov.cn/VISA), printed & signed
One white-background photo, 33×48 mm

🏥 Core medical documents (the key)

Invitation letter / admission notice from a Grade IIIA or designated international institution — must state: your full name, gender, date of birth, passport number; diagnosis summary; treatment plan & expected duration; estimated cost; hospital contact phone & address; official seal + authorized signature
Letter from your local doctor explaining your condition and why treatment in China is needed (with certified Chinese/English translation)

💰 Financial proof

Bank statement showing ≥ US$10,000 (recommended: 120% of estimated treatment cost)
Bank statements / credit card records / sponsor letter as applicable

👨‍👩‍👧 Companions & extras

If your health is frail or treatment involves surgery, we strongly recommend a companion comes with you — recovery is easier with a familiar face, and the S2 route explicitly allows accompanying caregivers
Accompanying family: max 2 immediate family members; need notarized relationship proof + hospital caregiver letter
Return flight reservation & accommodation proof
Travel medical insurance (recommended ≥ €30,000 incl. medical evacuation)

Process

Seven steps, in order

Hospital invitation letter for a China medical visa being signed

The hospital invitation letter is the key document

Only the hospital can issue it — and that is exactly what we coordinate for you.

Hospital track (4–8 weeks before)

Contact the target hospital's international department → submit medical records & imaging → remote video consultation → receive the formal medical certificate + invitation letter. This typically takes 2–4 weeks — don't leave it late.

Apply online

Complete the form on COVAS (consular.mfa.gov.cn/VISA) → select S2, purpose "Medical Treatment" → upload scanned documents → save your application number.

Pre-review (1–3 working days)

Missing documents are flagged by email — respond quickly.

Submit in person + fingerprints

Book at the nearest Chinese embassy/consulate or CVASC center. Bring originals and copies. Applicants aged 14–70 give fingerprints. Pay the fee.

Processing

Standard: 4–5 working days. Express: 2–3 days (+50% fee). Same-day: 1 day (+100%, urgent medical cases only).

On arrival in China

Complete accommodation registration within 24 hours (hotels do it automatically; private stays require a police station visit). Then report to the hospital's international department with passport, visa, invitation letter and medical records.

If treatment runs long

Apply for an extension at the local exit-entry administration at least 7 days before your permitted stay ends; total stay cannot exceed 180 days on S2. Longer treatment requires leaving China and re-entering on an S1.

Avoid rejection

Why S2 applications get refused — and how we prevent it

Common rejection reason	How we help
Incomplete medical documents	We verify the invitation letter contains every required element (diagnosis, plan, duration, cost, seal, signature) before you apply. Checklist available →
Insufficient funds shown	We advise the right financial-proof format covering ~120% of estimated cost.
Unclear treatment purpose	Your local doctor's letter + hospital invitation together tell a consistent story.
Hospital not properly qualified	We only work with Grade IIIA hospitals and designated international institutions.
Poor translations	Non-Chinese documents must be professionally translated — AI drafts, human-verified for key information.

Critical cases: Life-threatening emergencies can apply for humanitarian expedited processing (appointment within 24 hours).
Important: We assist with process coordination and document checklists. We never guarantee visa approval and never assist with irregular entry. Requirements change — always verify with the hospital and your nearest Chinese embassy/consulate.
