DO NOT go through this agency! They are thieves. I was never paid my contract completion bonus and they just ignore my phonecalls and emails.
The agent I dealt with, Jane, is the most incompetent agent ever. She gave me no help whatsoever in securing a visa. She doesn't know what she's doing. I had an endless amount of grief getting to shanghai and when it came time to leave, they promised me the money would be in my account, but it never came through. DO NOT go through this agency!!!
