I'm looking at a Chinese visa application right now. Do I need to submit any proof of my itn when submitting the application? Will including itns showing multiple entries into China increase my chance of getting a multi-entry Visa? As a UA 1k, I can book/change/cancel multiple awards into China for no extra fee.
You don't need to include an itin, but photocopying your past China visas (yes, even if they are in the same passport) is a nice touch. Also, if you want a 2-year (F) visa, try to either get or write your own invitation letter.
