Quick Answer
You may not need a visa at all if you are from one of the eligible countries. China offers two main visa-free pathways:
- • 240-hour (10-day) transit visa-free access for citizens of 55 countries — ideal if you are flying into Shenzhen from a third country and have an onward ticket to another destination.
- • 30-day unilateral visa exemption for citizens of 50 countries — you can fly directly from your home country without needing an onward ticket.
Note: The 55-country transit list includes all 50 countries on the unilateral exemption list, plus a few others (e.g., UK, US, Canada are on the transit list but not on the unilateral exemption list). Check both sections carefully.

30-Second Check: Do You Need a Visa?
1. Is your country on the 50-country visa-free list? (All EU/UK/US/Canada/Australia/Japan/Korea etc.)
✅ Treatment within 30 days? → No visa needed, fly straight to Shenzhen
⏳ Treatment needs more than 30 days? → You need an S2 visa → Medical Invitation Letter required
2. Departing from Country/Region A, transiting through China to Country/Region B (A ≠ B), with an onward ticket?
✅ 240-hour transit visa-free (10 days) — suitable for short consultations only. For treatment >10 days, S2 visa & invitation letter needed
3. None of the above apply?
• Treatment under 30 days → L visa (tourist) usually works
• Treatment over 30 days → S2/S1 visa needed → Medical Invitation Letter required
1. 240-Hour Visa-Free Transit
China extended its transit visa-free stay from 144 hours to 240 hours (10 days) for citizens of 55 countries. This is ideal for short medical visits.
How it works: You fly into Shenzhen (or another eligible city) from a third country and can stay for up to 10 days without a visa. You must have a confirmed onward ticket to a third country — not the country you departed from.
Eligible countries include:
…and more. The full list includes all EU/Schengen countries, plus Russia, UK, US, Canada, Brazil, Mexico, Australia, New Zealand, Japan, South Korea, Singapore, UAE, and others.
Key requirement: You must have a confirmed onward ticket. You cannot use this policy for round-trip tickets to the same country (e.g., UK→HK→Shenzhen→UK ❌, but UK→HK→Shenzhen→Japan ✅).
Entering Shenzhen from Hong Kong
Since November 5, 2025, the Guangzhou-Shenzhen-Hong Kong Express Rail Link West Kowloon Station has been added as a 240-hour transit visa-free entry port. You can now take the high-speed rail from Hong Kong to Shenzhen under this policy — provided you flew from a third country/region to Hong Kong, and your onward destination differs from your departure point.
Shenzhen now has3 ports for 240-hour transit visa-free entry: Bao'an International Airport, Shekou Port, and West Kowloon High-Speed Rail Station.
Sources: NIA — 240-Hour Visa-Free Transit Policy (55 countries, 65 ports); NIA — Unilateral Visa Exemption (50 countries)
The high-speed rail from Hong Kong to Shenzhen takes as little as 14 minutes — many Hong Kong residents take advantage of this for health checkups and dental care. See the cross-border checkup guide →
2. 30-Day Visa Exemption
China now offers unilateral visa exemption for up to 30 days for citizens of 50 countries. Unlike the transit policy, this does NOT require an onward ticket to a third country — you can fly directly from your home country.
This is the easiest option for medical visitors. If your country is on the list, simply fly to Shenzhen with your passport (valid for 6+ months) and you're good to go.
Validity note: The visa waiver is currently valid through December 31, 2026 for most of the 50 countries — with two exceptions: Brunei has no expiry, and Russia has been extended through December 31, 2027. Check the latest updates before you travel.

3. Medical / Private Affairs Visa (S2 for Short-Term, S1 for Long-Term)
If you need medical treatment in China and plan to stay longer than 30 days — or if your country is not on the visa-free list — you will need an S-category visa.
Important: M visa is for business/commercial trade, not for medical treatment. The correct visa for medical travel is S2 (short-term) or S1 (long-term).
S2 Visa (Short-Term Medical / Private Affairs)
- For patients requiring medical treatment lasting up to 180 days
- Required: Official Medical Invitation Letter from a recognized Grade A, Level 3 hospital in China
- Valid passport (6+ months validity, 2+ blank pages)
- Completed visa application form + recent photo
- Bank deposit certificate (typically ≥ USD 10,000 or equivalent)
- Overseas medical insurance covering your treatment period in China
- Apply at your local Chinese embassy/consulate — Processing time: 4 business days (urgent: 2–3 days)
S1 Visa (Long-Term Medical / Private Affairs)
- For patients requiring treatment exceeding 180 days
- Requires a Major Disease Notification or long-term treatment certificate from a Grade A, Level 3 hospital
- After entering China on an S1 visa, you must apply for a Foreigner's Residence Permit within 30 days
Short-Stay Alternative: Tourist Visa (L Visa)
If your treatment will last less than 30 days and your country is not on the visa-free list, a Tourist Visa (L Visa) is usually the simplest option — you do not need a separate "medical visa" for short stays.
⚠️ Note: The L Visa is primarily for tourism. Short-term checkups and outpatient visits are generally fine, but if you need inpatient treatment or surgery, check with your local Chinese embassy/consulate in advance whether an S2 visa is required — using the wrong visa type may cause legal issues.
