How to get an Invitation letter | PU letter in China

A lot of people ask me how to come to China during the period of Novel Coronavirus (COVID-19).  The answer is: It’s very complicated, you have to apply for the Invitation letter (PU letter) in China. In this article, we will explain everything you need to know about PU letter application in Shanghai.

How to come to China?

Since the rapid spread of COVID-19 across the world, China government has decided to temporarily suspend the entry into China by foreign nationals holding visas or residence permits still valid to the time of this announcement, effective from 28 March 2020. Only the foreigners who engage in necessary reasons (economic, trade, scientific, or technological activities, as well as for urgent humanitarian assistance) have the chance to come to China.  

According to the announcement, the foreigners need to apply for an Invitation Letter (PU Letter) issued by the China Foreign Affair Office, but the Official Office has strict standards for judging whether it is necessary to come to China or not. Usually, only the senior managers of Medium and Large Enterprises or the technique researchers of key projects have a chance of getting approval from the Government.

Even if the foreigners who are allowed to enter China are required to present a nucleic acid test report authorized by the Chinese government within 5 days before entering China to board the airplane. When foreigners enter Mainland China, they also need to be quarantined for 14 days as the observation period mandated by China‘s health authorities.  You can read this article to know the Specific announcements of the negative COVID Test before flying to China and the Countries list.

In 2021, more and more cities and provinces in China have started to adopt the new 14+7 policy, which means the Foreign Arrivals will be tested for COVID-19 a total of 4 times. The nucleic acid test is performed on the first, 7th, 14th – and then again on the 21st day after entry.

New Policy for the Foreigners who inoculated with COVID-19 vaccines produced in China

It is good news in 2021, you don’t need the PU/TE letters if you have been insulated with the Vaccines made in China.

From 15th, March 2021, if you have been inoculated with COVID-19 vaccines produced in China, the Invitation Letter (PU/TE) is no longer required if you want to enter Mainland China.

Meanwhile, the Chinese Embassy in the different countries will provide the following facilitation for visa applicants inoculated with Chinese COVID-19 vaccines (having taken either two doses of inactivated vaccines with the stipulated gap in between, or a single-dose vaccine at least 14 days prior to the application).

How to improve PU letter pass rate in China

The chance of failure is high for the PU letter application pass rate. Due to the Policy of temporarily suspend the entry into China, it is best that the entity which applies the PU letter is a High-technology enterprise in China. That means, the High-tech Companies don’t have to provide complete tax records in the past year for the Foreign Affairs Office.

If you have a WFOE without the High-technology certificate in China, you’d better provide the tax records in the past year to the Foreign Affairs Office.

For the Annual Report of your company, you can visit the official website by using the Electronic Business License and the code of CA to download the documents.

Answer: The notification letter of a foreigner’s work Permit is for the Z Visa by the Chinese Embassy or consulate. When you come to China, you should apply for a work permit and residence permit in the city where you are working.


As far as we know, China has not relaxed the application conditions for PU letters for the other countries, and the pass rate has not increased significantly. The small companies will be refused and suspend their PU letter applications in the second step. But, if you really need to come to Mainland China, why not try? The sooner you apply, the better it will be.

    What is difference between PU letter and TE invitation letter

    1. BaseInShanghai

      PU or TE letter depends on the purpose of coming to China.
      Normally, PU letter is to apply for the M or Z Visa, or Q1/Q2 Visa(Commerce Trading/working). TE letter is to apply for the Visa F (Communication/Vist/Investigation).
      Sometimes, different countries need different Invitation letters issued by the Chinese Government.

  11. clovis

    This is a joke. They accept now people who have been inoculated with the Chinese Vaccine, but the problem is that it is not available in most of the listed countries. hahahahah

    1. BaseInShanghai

      The United States decreed the ban on exporting vaccines to other countries. But China has pledged to send roughly half a billion doses to 45 countries, according to the Associated Press. As of mid-February, China reportedly shipped over 46 million doses of Chinese-made vaccines abroad. China has made great efforts and contributions.
      So, this is your idea of a joke.

      1. clovis

        Almost a month and the vaccines are still not available in the countries they listed. Where are the 46 million doses? The move was just to force those countries to buy chinese-made vaccines, not to actually help.

        1. BaseInShanghai

          China has 1.4 billion people, but how many people have been vaccinated? Everybody needs the Vaccines but only one in ten people get.

          You need to respect the country that can offer the Vaccines for the other countries!

  12. Caroline

    I have been offered a job in China and have gathered all my documents. Now the school have advised me that the chance of getting me visa approved is very low. How can I improve this, does it depend where you come from and which part of China you are going to? Is there a shortage of English teachers in certain areas of China?

    1. BaseInShanghai

      Yes, China is a big country. So It is urgent to change the situation of rural high school English education. In this case, you should ask the school to apply for the Notification Letter of Foreigner’s work permit in Foreign Expert Affairs and then apply for the PU letter from the FAO.

      1. Kenneth

        Hi, I was told by the school that the process to acquire Foreigner work permit and PU letter cost 30,000RMB? is that true?

  13. Netmae

    Do teachers who will work as a first timer in China still needs a PU letter even if they were inoculated by the Chinese vaccine already? or PU letter is not needed anymore?

    1. BaseInShanghai

      Where are you from? Normally if you inoculated Covid-19 Vaccines made in China, you don’t need the PU letter to come to China.

  14. waqas

    I need little help.
    I changed my company from Shenzhen to shanghai recently. I got the new work permit in shanghai but the told me to exit china for residence permit as my first entry in china was on student Visa. Now when my company is trying to apply for PU letter, They have asked to submit work permit notification Letter.
    I don’t understand how can i get that letter while i have a valid work permit with same company?
    Also is it possible to apply for Work permit notification letter while having a valid work permit ?
    Looking forward for your kind response.

    1. BaseInShanghai

      It is a strange question. If you are in China and have a work permit, why you need to exit China for the Residence permit?
      Why you need the PU letter? You can add our Wechat QR to explain the details with the expert.

    2. BaseInShanghai

      If you have a valid Work permit in China, you don’t need to apply for the Work permit notification letter.

  15. Venkiteswaran Ts

    Is Chinese Covid- 19 vaccine available in Nepal? If I take Chinese vaccination can I travel to china without PU letter from a Chinese company? I am from India

    1. BaseInShanghai

      Please contact the Chinese Embassy in Nepal to know the latest announcement.
      If you are from India, Yes. If you have been inoculated with COVID-19 vaccines produced in China, the Invitation Letter (PU/TE) is no longer required.

  16. laerte Fabiano de Mello

    I work 7 years in China I have work permit, but due to pandemic, i could not get into china, so my company ask me to work in their company in vietnam but now ask me to return to china but as my visa had expired, i am trying to renew the visa but with the PU letters, they denied said the company that work in china not and compatible with the requirements of PU LETTERS

    1. BaseInShanghai

      Only the Chinese company has the right to apply for PU letter for employees. In this case, firstly you need to contact your company to apply for the notification work permit in the FEA (Foreign Expert Affairs). Secondly, your company needs to contact the FAO for the PU letter.

  17. Louis

    I am currently based in shanghai with a residence and work permit valid till feb 2022.
    I saw the development regarding the PU Letter in order for my wife to join me based in Singapore.
    However, given that the chinese vaccine are not yet approved by authority in Singapore and Singapore is not yet listed as a location whom can apply for visa without PU letter even when my wife can be innoculated with chinese vaccine.
    Do you have any indication whether there will be any relaxation of opening for PU letter even without Chinese Vaccine?

    1. BaseInShanghai

      In Feb, the first batch of Chinese Sinovac vaccine purchased by the Singaporean government arrived in Singapore. Your wife can get the Chinese COVID-19 vaccines. Btw, I don’t think that China will open the door without PU letter.

  18. Mari

    I’m based in Iran and my husband lives in Shanghai. He also has resident permit visa.
    My question is: how can I come to China and visit my husband?
    Is it possible he send me an invitation?

    1. BaseInShanghai

      Recently, it is very difficult to apply for PU letter as a family member even if your husband works in Shanghai.
