Chefs working abroad, whether Chinese or western, must hold at least a third-class (advanced certificate). Because the foreign immigration bureau will accept your legal work permit for overseas employment according to the "chef certificate" you hold. If you don't have a chef's certificate to go abroad for research, you can register for the exam at the Vocational Qualification Certificate Technical Guidance Center (test center) under Ministry of Human Resources and Social Security in your place of residence or work. The examination is divided into two parts: theory and practice. Generally, I will take the theory test first, and then take the practice test a week later. Only when the theoretical and practical test scores reach 60 or above can they pass. Those who have obtained Grade 3 or above also have the requirements of working years, age and academic qualifications. For technicians (Grade II), papers 1 are required, and for technicians (Grade I), 2 papers are required. The specific regulations vary from place to place. You can consult the local examination center according to your actual situation.
