I had lived in three different Chinese cities — Chengdu, Hangzhou, and Shenzhen — over the course of seven years, and my Canadian employer required a police clearance certificate covering the full period across all three locations. I had no idea whether I needed three separate certificates or whether one city's bureau could issue a consolidated clearance. Your team confirmed that three separate applications were required, prepared a tailored document package for each city's public security bureau, and staggered the submissions to ensure the certificates would arrive within the same window. All three were successfully issued and my employer's verification process was completed without any delays.
