To get an invitation letter for a Chinese business visa, you must ask your registered corporate partner, client, or exhibition organizer in mainland China to draft and sign an official letter on their company letterhead. They must secure it with their registered corporate seal, known as a company chop, before scanning and emailing it to you.
How the Chinese corporate invitation system operates
The Chinese visa authorities require an invitation letter for an M-class business visa to verify that your trip is legitimate. It acts as a formal confirmation that a legally registered business in China is sponsoring your commercial activities, trade talks, or factory visits. The government uses this document to hold your host legally responsible for your conduct and schedule while you are inside the country.
The underlying rules of the Chinese corporate framework mean a basic email printout or a standard signed letter will not work. In China, a company signature carries very little legal weight on its own. True authorization requires the physical imprint of the corporate seal, which is a round, red stamp registered directly with the local Public Security Bureau.
The letter must contain precise, matching data that perfectly aligns with the details on your passport and your online visa application form. Any spelling mistakes, missing dates, or vague explanations of your business goals can trigger an instant rejection. This forces you to restart the online application process and delays your travel schedule.
The exact steps to secure your invitation letter
Obtaining a valid document requires close communication with your Chinese host, who must format the letter to meet strict consular standards.
- Provide your personal details to your host. Send your Chinese contact a clear scan of your passport information page, your exact job title, and your company name. They need this information to fill out the applicant section of the document.
- Finalize your travel itinerary with the company. You must provide your host with your exact entry and exit dates, the specific cities you will visit, and a clear breakdown of who is covering your travel and lodging expenses.
- Draft the text on official corporate letterhead. Ensure your host places all the text on their official company stationery. This paper must clearly display their registered Chinese address, operational telephone number, and corporate email.
- Apply the official corporate seal. Your contact must physically stamp the document using the round red company chop, and an authorized company representative must sign it by hand.
- Receive and print the high-resolution scan. Your host can scan the final stamped document and email it to you as a PDF. In most cases, the Chinese consulate accepts a clean, high-quality digital printout, though they reserve the right to request the original paper copy.
The government pre-approval exception you might encounter
A common mistake business travelers make is assuming that a standard company invitation letter is always enough for every single situation. Depending on your nationality, your specific industry, or the current policy changes at the local embassy, the consulate might demand a special document called a PU Letter or a TE Letter instead.
A PU or TE letter is an official invitation verification form issued directly by a Chinese government agency, such as the local Municipal Bureau of Commerce or the Foreign Affairs Office. If the consulate tells you that your standard corporate letter is insufficient, your host cannot fix this on their own. They will have to log into a government portal, upload your passport data, and wait several weeks for regional officials to approve and issue this state-level document.
To avoid a last-minute travel disaster, always check the latest notices on your specific Chinese visa application center website before requesting your paperwork. If your industry requires government pre-approval, you must tell your Chinese host to start the application with their local commerce bureau immediately, because these state-issued letters take much longer to process than a standard corporate note.
