Foreigners working in China need to apply for corresponding work permits and hold valid residence documents. However, foreigners may encounter difficulties in applying for work permits and residence documents due to various reasons, such as poor information and complicated procedures. At the same time, there may also be ambiguity or misunderstandings about issues such as the validity period and renewal of work permits and residence documents.

When foreigners sign labor contracts with Chinese employers, they may face problems such as unclear contract terms and insufficient protection of rights and interests. For example, regulations on wage payment, working hours, welfare benefits, insurance contributions, etc. may differ from foreigners' expectations. In addition, foreigners may not be familiar with China’s legal procedures and regulations regarding the resolution of labor disputes, making it difficult to safeguard their rights.

Foreigners working in China usually need to pay personal income tax. However, due to the complexity of tax policies and the diversity of personal circumstances, foreigners may encounter problems with tax declaration, tax payment methods, tax exemptions, etc.

Foreigners may also encounter some legal problems in their daily lives in China. For example, when renting a house, you may encounter problems such as the landlord not abiding by the contract and the deposit not being returned; when shopping, you may encounter product quality problems or damage to consumer rights; when traveling, you may face legal issues such as traffic violations and traffic accidents.
