Employment certificate: printed in English on company stationery with accurate company address and telephone number (if the company doesn't have stationery, you can edit it yourself), signed by the person in charge (please ask the personnel or company management to sign, but you or your peers can't sign each other), and stamped with the company official seal or personnel seal. Provide an on-the-job certificate with the applicant's position, monthly salary, working hours, purpose of this trip, travel date, vacation days, expense undertaker and other contents (see the template and format for details).

Business license: provide a copy of the business license within the validity period and affix the official seal (non-enterprise units can use the organization code certificate instead). The business license or organization code certificate must have the annual inspection seal of the latest year.
