Hi!
I am from Thailand. I have been in China for 1 year and 3 months. I first came here with a one-year L visa and then changed it to X visa as I wanted to study Chinese. Now I'm on the second X visa which expires in 1 week. I would like to change my X visa to F visa because I already finished studying Chinese and would like to stay longer look for a job here.
I would like to ask you the following questions:
1. I understand that I have to go back to my country to have my X visa changed to F visa, is that correct?
2. In my case, is it possible to get a one-year multiple entry F visa, with 90 day stays?
3. Besides an invitation letter, do I also need "Visa Notice Sheet" from an authorized organization in China? What is "Visa Notice Sheet" and how do I get it?
4. An invitation letter can be issued by any Chinese organization? Does it need any stamp or authorization from the Chinese government?
Any help or advice will be very much appreciated. Thanks in advance!
