Multiple entry 6 or 12 months

1. Jackie, based on what I know, the duration of stay is usually 30 days. Sometimes, the applicant may get 60 days or 90 days, but it is not common.
2. You can try again after you failed in first application.
3. There is no limit. You can enter China for multiple times within its validity.
4. The company can be any company from China.
5. I’m afraid letter issued by company in Malaysia or Singapore cannot work. It should be issued from a company based in China
