I am a Chinese citizen who plans to apply for a UK standard visitor visa in China to attend a conference in the UK in July 2019. I just finished my first job contract, which is at a U.S. university, and I will be employed as an instructor at another U.S. university in August 2019.
The time when I apply for UK visa and attend the conference is in the gap between the time I finish my first employment but have not yet begun my second employment. Is it okay that I provide the employment letter from my future employer?
Since I apply for the visa in China, must the employment letter be from a Chinese employer, even through I am a Chinese citizen and have savings of my own and have a permanent house with my parents?
