China M Visa (Business) Guide: Invitation Letters, Documents & Rules (2026)

What’s an M Visa?

The M visa (M stands for 贸易, màoyì — “trade”) is for commercial and business activities in China. It covers:

• Attending trade fairs and exhibitions (Canton Fair, CIFF, auto shows)
• Visiting suppliers and factories
• Business negotiations and contract signings
• Equipment installation and technical support
• Market research and business meetings

It does NOT cover:

• Employment or paid work (need a Z visa)
• Journalism or reporting (need a J visa)
• Studying (need an X visa)
• Pure tourism (use the L visa, or better, the visa-free policies if eligible)

If you’re going to China to check on your factory, walk a trade show floor, or negotiate with a supplier, the M visa is what you need.

The Invitation Letter: Your Ticket In

This is the single most important document in your application. A bad invitation letter = rejection. Period.

Who Can Invite You

The invitation must come from a registered Chinese business entity — your supplier, trade partner, exhibition organizer, or the company you’re doing business with. A personal invitation from a Chinese citizen won’t work for an M visa (that’s a Q visa).

What the Letter Must Contain

| Element | Details | |---|---| | Your info | Full name, gender, nationality, date of birth, passport number | | Visit purpose | SPECIFIC. “Attending Canton Fair Phase 1 (April 15-19, 2026) and visiting three supplier factories in Guangzhou and Foshan” — NOT “business meetings” | | Itinerary | Dates and locations for your activities in China | | Stay duration | Exact entry and exit dates | | Who pays | State clearly — “all costs covered by X company” or “applicant bears own expenses” | | Inviter’s company info | Full company name in Chinese, registered address, contact person name, phone number | | Signature + stamp | Handwritten Chinese signature plus the company’s official round seal (公章) |

The 2026 Handwriting Rule

A rule that started rolling out in 2025 and is now standard across most consulates in 2026:

Any supporting document from the Chinese company — the business license copy and the inviter’s ID copy — must have handwritten annotations directly on the copy.

The annotation should say, in Chinese: “此文件仅用于[申请人姓名]签证申请使用” (This document is for visa application use by [applicant name] only). Below that: handwritten Chinese signature + date.

This is an anti-fraud measure. Scammers were stealing business licenses and using them for fake invitations. The handwritten notation proves a real person at the company handled this specific document.

Is it annoying? Yes. Can you skip it? No. Send this requirement to your Chinese business partner early — it’s their job to provide, not yours.

Types of Invitation Letters

You might encounter several document types depending on your situation:

Standard company invitation: A letter on company letterhead with the official stamp and signature. This is fine for single or double-entry M visas at most consulates.

Exhibition invitation: If you’re attending a trade fair (Canton Fair, CIFF, Auto Shanghai), the event organizer can issue an official invitation with a serial number. These are generally accepted without additional verification.

Invitation Verification Letter (邀请核实单): Issued by the local Foreign Affairs Office, this verifies that the inviting company and the invitation are legitimate. Some consulates require this for multiple-entry M visas. Your Chinese partner applies for this through their local FAO — it takes 4-5 working days.

PU/TE Letter: Issued by provincial-level Foreign Affairs Offices for sensitive cases or long-term multiple-entry visas. Your partner needs to submit an application through the government system. These take longer but carry more weight.

Ask your Chinese partner which type their consulate typically accepts. If they do business with foreign visitors regularly, they’ll know.

The Full Document Checklist

Your Documents

• [ ] Passport — valid 6+ months, at least 2 blank visa pages
• [ ] Completed COVA online application form (cova.cs.mfa.gov.cn)
• [ ] One passport photo — white background, 48mm × 33mm, no glasses, both ears visible
• [ ] Photocopy of passport data page

From Your Chinese Partner

• [ ] Invitation letter (original, stamped, signed)
• [ ] Business license copy (营业执照) — must show business scope, with handwritten annotation, signature, date
• [ ] Inviter’s Chinese ID card copy (front and back) — with handwritten annotation, signature, date

From Your Employer/Clients

• [ ] Cover letter from your company — introduces you, your position, purpose of trip, itinerary summary, company profile
• [ ] Proof of business relationship — recent emails, contracts, invoices, purchase orders, payment records between your company and the Chinese company
• [ ] Your company’s business registration or incorporation certificate (stamped)

If you’re self-employed or an independent consultant, provide your business registration, client contracts, and proof of professional activity.

Step by Step Application

Step 1: Get Documents from Your Chinese Partner

Start this 3-4 weeks before you plan to apply. Chinese companies can be slow with paperwork, and the handwritten annotation requirement means an actual person has to physically do it. Don’t leave this until the last week.

Step 2: Fill COVA Online

Go to cova.cs.mfa.gov.cn. Select your country and the consulate you’ll use. Choose “M” as visa type. Upload scans of your supporting documents where prompted. Triple-check your passport number and name spelling — a typo here means restarting the whole thing.

Step 3: Book Appointment

Go to the China Visa Application Service Center (CVASC) website for your jurisdiction. Appointments typically open 1-2 months in advance. Trade fair season (March-April for Canton Fair, September-October for autumn fairs) is peak time. Book early.

Step 4: Attend Appointment

Bring originals AND photocopies of everything. The visa center keeps the copies. Dress professionally — it shouldn’t matter, but it does at some centers.

You’ll likely be fingerprinted (unless you’re exempt for short-term single/double-entry applications under new 2026 rules). Pay the visa fee — varies by nationality due to reciprocity agreements.

Step 5: Wait

| Processing | Time | |---|---| | Standard | 4-7 working days | | Express | 2-3 working days (extra fee) | | Rush | 1-2 working days (limited availability) |

Track your application with the receipt number. Collect your passport when notified. Check the visa immediately — verify your name, passport number, number of entries, and duration of each stay.

How to Get a Multiple-Entry M Visa

A multiple-entry M visa is the holy grail if you visit China regularly for business. In 2026, here’s what helps:

• Previous China visas in your passport, used without overstaying
• Sustained business relationship — contracts and invoices showing years of dealings with the same Chinese company
• Applying at the same consulate where you got previous visas
• A strong PU/TE letter from the provincial FAO supporting multiple entries
• Applying for a longer validity — some consulates now issue 1-year, 2-year, or even 5-year multiple-entry M visas to qualified applicants

First-time applicants usually get single or double entry. Don’t expect multiple entry on your first try unless your business case is exceptional.

Common Rejection Reasons

1. Vague purpose. “Business meetings” is not specific enough. Name actual companies, events, or projects.

2. No handwritten annotations on supporting documents. This is the #1 2026-specific rejection. Your Chinese partner must write on those copies.

3. Business license doesn’t show scope. If the inviting company’s business license doesn’t include the relevant industry, the consulate questions the legitimacy of the invitation.

4. Mismatched itineraries. Your cover letter says 5 days. Your invitation says 14. Your flight booking says 7. Pick one number and make everything consistent.

5. Insufficient proof of business relationship. A single email from 3 years ago isn’t enough. Show ongoing commercial activity.

6. Wrong visa type. Applying for an M visa for something that should be an F visa (non-commercial exchange) or Z visa (actual employment).

FAQ

Final Word

The M visa process is paperwork-heavy but predictable. The key is your Chinese partner — they need to provide proper documents with the right stamps, signatures, and now those handwritten annotations. A partner who’s invited foreign visitors before will know the drill. If they’ve never done it, send them the requirements early and budget extra time for back-and-forth.

Once you have the visa, the hard part is over. Chinese immigration is efficient at processing M visa holders — they want business travelers to have a smooth experience.
