Whether foreigners need to be interviewed for visa applications in China depends on the specific circumstances. Normally, most visa applications do not require an interview, and applicants only need to submit complete documents. But in the following situations, an interview may be required:
1. Individuals applying for a Chinese visa for the first time.
2. Individuals who have applied for a Chinese visa but have been denied it.
3. Individuals whose visa type does not match their previous application or whose visa validity period is insufficient.
4. Applications with incomplete or questionable materials.
5. Apply for specific types of visas such as work visa (Z visa), study visa (X1 visa), etc.
If an interview is required, applicants are usually required to make an online appointment in advance and bring the required documents to the visa application center or consulate for the interview.
