A work visa is required for persons wanting to work in China for pay.  It is also issued to aliens who come to China for commercial entertainment performance. It is only granted if you and the employer meet certain requirements.  First, the organisation must be accredited to employ foreigners. You must meet the requirements as a 'foreign expert' and the employer must obtain a certificate stating that you comply. The most common employment is teaching English for which the minimum qualifications are stated as having English as a first language and having at least a Bachelors degree and two year teaching experience. The age limit for male applicants is 24 - 65, and 24 - 55 for female applicants. However, there is some flexibility in these requirements so if you can find a willing employer they still have a chance of obtaining approvals for you.

The employer will send you a government issued Employment Permit and Visa Notification Letter which you must submit with a photocopies with your application. Accompanying family members should apply for new Q1,S1 or S2 visa submitting invitation letter from the relative with work Z in China and a 'proof of relationship'  i.e. their marriage certificate for a spouse, or birth certificate for a child.
