The Chinese Visa Application Service Centre in London will start a partial resumption of service from 16th March 2021.

Whilst applications are limited to certain groups (full details HERE), this includes those visiting China for ‘economic, trade, scientific, or technological purposes’. 
 
The primary requirement is an invitation letter or ‘verification confirmation of invitation’ issued by the Foreign Affairs Office of the provincial government or the provincial Department of Commerce of the intended place of visit.

For those returning to work in China, a ‘notification letter of foreigners’ work permit’ is required, in addition to an invitation letter (as outlined above).
 
If you would like support or advice on obtaining an invitation letter, please email: enquiries@cbbc.org
