Because the work content of “specialized or technical” foreign professional workers already includes the business management category of “supervisors of businesses invested by overseas Chinese or foreigner(s)” and the eligibility criteria of employing specialized or technical foreign professional workers (including educational background and work experience of foreigners, salary conditions, qualifications of employers) is stricter than the criteria of employing supervisors of businesses invested by overseas Chinese or foreigner(s); therefore, if the salary conditions and turnover volume of the employer are all in accordance with the “specialized or technical” approval criteria, then there is no need to go through the process of handling “specialized or technical” dismissal and switch to newly-hired “supervisors of businesses invested by overseas Chinese or Foreigner(s).”
