Visa application tips 签证办理

To ensure a smooth process, apply for your visa as early as possible (at least 1–2 months before travel). Rules and processing times vary by country, so check your local Chinese embassy/consulate for specifics.

 

1. Visa Types for Attendees

• Tourist ("L") Visa (Recommended for most attendees):

  • No invitation letter required (simplest option).

  • Validity: 30 days to 10 years (depends on nationality, entry frequency, and embassy discretion).

  • Cost: 60– 60–140 (varies by nationality/processing speed).

  • Tip: Some consulates issue multi-entry L visas for frequent travelers (e.g., 1-year/10-year validity for eligible passports like the US).

• Business ("M"/"F") Visa:

  • Required if attending paid work/academic activities (e.g., speaking for a fee).

  • Invitation letter from a Chinese host (e.g., conference organizer) may be needed.

  • Alternative: Apply for an L visa if your stay is short and unpaid.

• Other Visas (Less common for conferences):

  • Student ("X") Visa: For long-term study programs.

  • Work ("Z") Visa: Requires employer sponsorship and medical checks.

2. Key Requirements

• Documents: Passport (6+ months validity), application form, photo, flight/hotel bookings.

• Invitation Letter (if applicable): Some consulates may request one for M/F visas—confirm with your embassy.

• Health Declarations: COVID-19 testing/quarantine rules have been lifted, but check for updates.

 

3. Where to Apply

• Chinese embassies/consulates in your home country.

 

4. Recent Changes (2024–2025)

• Tourist visas (L) are widely available again, including multi-entry options.

• Faster processing: Some embassies offer express services (3–5 days) for urgent trips.

• 10-year L visas: Still available for citizens of the US, Canada, and other eligible countries.

 

5. Pro Tips

• Double-check your visa duration/entries (e.g., a "single-entry" visa expires after one use).

• Hong Kong/Macau arrivals: These SARs have separate entry rules; a Chinese visa is not required if staying only in HK/Macau.

• For the latest info: Contact your local Chinese embassy or use VisaForChina.
