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

Canton Fair Phase 1 opens 15 April 2026 in Guangzhou. If your buyer badge is registered and the flight is paid but your passport pages are still empty, you have roughly four working days of standard processing between you and the check-in counter, plus however long your Chinese partner needs to print, stamp, sign, and handwrite on a small stack of paper. The M visa is the document that closes that gap, and it happens to be the one visa category where the paperwork waiting for you on the China side matters more than the paperwork you fill out yourself.

This guide walks the whole thing end to end: what the M visa covers, what the invitation letter has to say, the 2026 handwritten-annotation rule, the full document checklist, and the exact spots where applications get bounced. Fees, fingerprint rules, and processing times below are stated as of 2026-07 and carry expiry dates, so re-check the consulate page for your jurisdiction in the week you actually apply.

What the M Visa Covers, and What It Does Not

Walk a trade show floor, sit across a table from a parts supplier in Foshan, sign a purchase contract, supervise a machine install, or run market research meetings in Shanghai. Those are M visa activities. The category tracks commercial and trade work, listed on the form under the heading maoyi, which simply means trade.

A typical M visa itinerary looks like this:

• Attending trade fairs and exhibitions (the Canton Fair, CIFF in Shenzhen, Auto Shanghai)
• Visiting supplier factories and auditing production lines
• Negotiating and signing commercial contracts
• On-site equipment installation and after-sales technical support
• Sourcing trips and business development meetings

The M visa is the wrong stamp for:

• Taking a salary or paid role in China (that is a Z visa)
• Reporting or journalism (J visa)
• Enrolling in a course (X visa)
• A holiday with no business purpose (L visa, or the unilateral visa-free entry if your passport qualifies)

If the reason you are boarding the plane is commercial, the M visa is the category. Confirm the boundary for your specific activity on the consular guidance page; verify at consular.mfa.gov.cn/VISA as of 2026-07.

Sightseeing on an M visa is fine as long as business stays the primary reason for the trip. Border control does not audit whether you spent Tuesday afternoon at the Bund instead of a meeting room.

The Invitation Letter Is the Real Application

Hand the consulate a weak invitation letter and the rest of your file does not get a fair read. Everything below has to sit on one or two pages from your Chinese partner.

Who Is Allowed to Invite You

The letter has to come from a registered Chinese business entity: your supplier, your trade partner, the exhibition organiser, or the company you are negotiating with. A personal invitation from a Chinese friend or relative does not qualify for an M visa; that route is the Q visa for family visits.

What the Letter Has to Say

| Element | What to put in it | |---|---| | Your details | Full name, gender, nationality, date of birth, passport number | | Purpose | Specific. “Attending Canton Fair Phase 1 (15 to 19 April 2026) and auditing two supplier factories in Guangzhou and Foshan,” not “business meetings” | | Itinerary | Dates and cities for each activity in China | | Length of stay | Exact entry and exit dates | | Who pays | Plainly stated: “all costs borne by [company]” or “applicant covers own expenses” | | Inviter details | Full Chinese company name, registered address, contact person, phone number | | Signature and seal | A handwritten Chinese signature next to the company’s round official seal |

The 2026 Handwritten-Annotation Rule

A requirement that started rolling out through 2025 and is now standard at most posts in 2026:

Every supporting photocopy that comes from the Chinese company, specifically the business license copy and the copy of the inviter’s ID card, must carry a handwritten note written directly on the paper.

The note, in Chinese, reads: 此文件仅用于[申请人姓名]签证申请使用, which translates to “this document is for the visa application of [applicant name] only.” Under that line goes a handwritten Chinese signature and the date.

The point of it is fraud control. Stolen and recycled business licenses were being used to back fake invitations, so the consulate wants proof a real person at the company handled this exact document for this exact applicant. Annoying to coordinate? Yes. Optional? No. Forward the requirement to your Chinese partner the same day you start the process, because producing it is their job, not yours, and it needs an actual human at their end with a pen.

Wording expectations differ slightly by consulate, so confirm the exact phrase your post wants. Verify at the visa centre notice board for your jurisdiction on visaforchina.cn as of 2026-07.

Four Kinds of Invitation You Might See

Plain company letter. Letterhead, official seal, signature. Enough for a single or double entry M visa at most consulates and the format most first-time applicants use.

Exhibition invitation. If you are going to a trade fair, the event organiser can issue an official invitation carrying a serial number. These usually clear without extra verification, which is one reason fair-goers find the M visa easier than a generic business visit.

Invitation Verification Letter (yaoqing heshi dan). Issued by the local Foreign Affairs Office, it confirms the inviting company and the invitation are genuine. Some consulates ask for it on multiple-entry applications. Your Chinese partner requests it through their local FAO; expect four to five working days for it to come back.

PU or TE letter. Issued by a provincial-level Foreign Affairs Office for sensitive cases or long multi-year multiple-entry visas. Your partner files through the government system. Slower to obtain, but it carries more weight with the visa officer.

Ask your partner which of these their consulate normally accepts. A company that hosts foreign visitors every quarter already knows the answer.

The Application, Step by Step

Step 1: Pull documents from your Chinese partner

Start this three to four weeks before you plan to lodge the application. Chinese firms move at their own pace with paperwork, and the handwritten annotation means a real person has to physically pick up a pen. Do not leave it to the final week.

Step 2: Fill in COVA online

Go to cova.cs.mfa.gov.cn, pick your country and the consulate that will handle you, and choose M as the visa type. Upload scans of the supporting documents where the form asks. Triple-check the passport number and the spelling of your name against the machine-readable line. A typo here means tearing the form up and starting over.

Step 3: Book the appointment

Use the China Visa Application Service Centre (CVASC) site for your jurisdiction, or the AVAS appointment system at avas.mfa.gov.cn where your post uses it. Slots typically open one to two months out. Trade fair season is the crush: March and April for the spring Canton Fair, September and October for the autumn fairs. Book the moment your documents are in hand.

Step 4: Show up

Bring originals and a full set of photocopies; the centre keeps the copies. Dressing like you mean business should not matter, and at some centres it quietly does.

On fingerprints: as of 2026-07, applicants for short-term visas, meaning a permitted stay of 180 days or less, are exempt from fingerprint collection. That exemption covers single, double, and multiple-entry M visas, and China extended it through 31 December 2026 by an embassy notice dated 18 December 2025. Long-term work and study visas still need fingerprints. Verify at sr.china-embassy.gov.cn as of 2026-07, since individual posts publish their own notice.

You pay the visa fee at the counter. The amount follows reciprocity, so it changes with your passport.

Step 5: Wait, then check the stamp

| Processing | Typical time | |---|---| | Standard | 4 working days | | Express | 2 to 3 working days, extra charge | | Rush | 1 to 2 working days, limited posts |

Track the case with the receipt number and collect the passport when the centre messages you. Open it on the spot. Read your name, the passport number, the number of entries, and the duration of each stay before you leave the counter. Fixing a misprint later costs you another trip.

Getting a Multiple-Entry M Visa

A multi-entry M visa is what regular visitors want, because it removes the paperwork cycle from every trip. In 2026 the things that move the officer toward multiple entries are:

• Earlier China visas in the same passport, used cleanly with no overstay
• A sustained commercial relationship, shown by contracts and invoices spanning more than one year with the same Chinese company
• Applying at the same consulate that issued your previous China visas
• An Invitation Verification Letter or a PU/TE letter backing the request
• Asking for a longer validity up front; qualified applicants now see one-year, two-year, and in some cases five-year multiple-entry M visas

First-time applicants normally land a single or double entry. Treat multiple entry on a first attempt as a long shot unless the business file is unusually strong.

Why Applications Get Rejected

1. Vague purpose. “Business meetings” reads as a placeholder. Name real companies, named events, or a named project.

2. No handwritten annotation. The single most common 2026-specific refusal. The copies from your Chinese partner must have the note, the signature, and the date written on them.

3. Business scope does not match. If the inviting company’s license does not list the relevant industry, the officer questions whether the invitation is genuine.

4. Numbers that disagree. Your cover letter says five days, the invitation says fourteen, the flight booking says seven. Pick one figure and make every document match it.

5. Thin proof of relationship. A single email from three years ago is not a relationship. Show ongoing commercial activity.

6. Wrong category. Filing an M visa for what is really non-commercial exchange (F) or actual employment (Z).

FAQ

Before You Book the Flight

Two things decide whether this takes three weeks or three months: how fast your Chinese partner returns the stamped, signed, handwritten-annotated package, and whether the day counts line up across every page in the file. Lock those two down first and the rest is mostly a queue you wait in.

The fee reduction, the fingerprint exemption, and the handwritten-annotation expectation all carry 2026 expiry dates. Open the consulate page for your jurisdiction one more time in the week you lodge the application, and trust that over whatever you read in a blog, this one included.
