International students should enter China within the period specified on their visas. They are subject to frontier inspection and customs and health inspections according to Chinese law. International students should, within twenty-four hours of entry into China, go through temporary accommodation procedures. Those holding Visa X should, within 30 days of entry, obtain temporary residence cards from the Public Security Bureau. Upon arriving at school, students must go to a local health department to get their Physical Examination Record checked. If a Physical Examination Record is found to be out of date, or if some items are not properly documented or unchecked, the student must have the missing items properly documented or retake the physical examination. Only after passing the inspection by the Public Health Department can students begin their residence and admission procedures.
