How long can a foreigner's work permit be valid for?

The validity of a foreigner's work permit depends on a number of factors, as follows:

For high-end talents in category A, a work permit can be applied for a maximum of 5 years;

For professionals in category B, a work permit can be applied for a maximum of 2 years, and for other foreigners (category C), the validity period of the residence permit shall not exceed 1 year at the longest.

Meanwhile, the validity period of the work permit shall not exceed the validity period of the business license or registration certificate or government approval, nor the validity period of the labor contract or letter of assignment, nor the validity period of the work applicant's passport or other international travel document that can replace the passport, etc.

In addition, if the foreigner has already obtained permanent residence in China, he/she does not need to apply for a work permit. If necessary, a five-year work permit can also be applied for. If a foreigner comes to China to complete a short-term work assignment and stays in the country for no more than 90 days, he/she is required to apply for a "Work Permit for Foreigners Coming to China" (90 days or less).

In general, the validity of a foreigner's work permit depends on a number of factors such as the type of visa, the type of work, the validity of the passport and the validity of the relevant documents. The exact length of the validity period will also be affected by local policies. If necessary, consult with the local authorities or a lawyer for assistance.
