Foreign students who come to study in China must hold an ordinary passport and study (X1 visa or X2 visa) visa to enter the country. The period of stay for the X1 visa is 30 days after entering the country, and a residence permit must be applied for before that. Failure to apply for an overdue visa constitutes an illegal stay. X2 visa stay period is subject to the period of stay after entry indicated on the visa. An expired visa constitutes an illegal stay. Depending on the seriousness of the circumstances, illegal residence will be subject to relevant penalties such as administrative warnings or fines from the public security organs. Under normal circumstances, foreign students should not enter the country with other types of visas. Students who hold other types of visas due to personal reasons should apply for study visas or study residence permits as soon as possible after registering at the school. All the consequences caused by not holding a study visa shall be borne by the students.
