How to Get a Chinese Business Invitation Letter (PU Letter)

For Nepali business travelers planning to visit China in 2025, obtaining a Chinese Business Invitation Letter (PU Letter) is one of the most critical steps in the China Business Visa (M-Visa) process. The PU Letter is an official government-verified invitation issued through Chinese authorities, confirming that the traveler has been formally invited for legitimate business purposes. It is a key document required for visa approval, particularly for first-time applicants or those applying for multiple-entry business visas.
The PU Letter is typically issued by the Foreign Affairs Office (FAO) or an authorized local government department in China at the request of a registered Chinese company, trading partner, or organization. The inviting company must first apply on behalf of the Nepali applicant through their provincial Foreign Affairs Office. The Chinese government reviews the application, verifies the legitimacy of the company, and then issues the PU Letter — a document that confirms the purpose of visit, duration, and the relationship between the inviter and invitee.
To obtain a PU Letter, the inviting Chinese company must submit several documents to their local FAO, including:
Copy of the applicant’s passport and personal information page
Applicant’s employment certificate or business registration in Nepal
Purpose of visit (e.g., trade fair, supplier meeting, factory inspection)
Company’s business license (营业执照) and registration number
Proposed travel itinerary and stay duration
Proof of past cooperation or trade relationship between both parties
Once the application is reviewed and approved by the authorities, the PU Letter is issued — either in digital (PDF) or physical copy format. This document must then be attached to the China Business Visa (M-Visa) application and submitted to the Chinese Visa Application Service Center (CVASC) in Kathmandu, located at Rising Mall, Kamaladi. Without the PU Letter, the embassy may not accept the application, especially for multiple-entry or long-term visas.
The processing time for a PU Letter usually takes 5 to 15 working days, depending on the province and the type of business. Some regions with high trade activity, such as Guangzhou, Shanghai, and Shenzhen, process them faster for verified partners. However, since only the Chinese side can apply for the PU Letter, Nepali applicants should communicate clearly with their hosts in China and provide accurate passport and company details.
