An online seminar will be held on 28 July with the authorities in Guangzhou titled: "How to Return to China". The Shenzhen Foreign Affairs Office held a similar online seminar a few weeks ago that wasn't too helpful and just confirmed what we already knew but at least they confirmed there was a process and a web site detailing it. It does highlight the fact that the new Invitation Letters that we need to support our new entry visa applications are dealt with by Foreign Affairs Offices on a very local basis. In this case, the city of Guangzhou. So if you're heading there then this online seminar may be useful.
