IR5 移民簽證，媽媽在中國， civil documents 的Police Certificates 是什麽？

請教壇主：
給在中國的媽媽申請移民簽證， 今天收到郵件，要先用PDF電郵所有civil documents . 其中一項叫 police certificates .
網上注解是這樣的：
If you are 16 years of age or older, you must submit a photocopy of a police certificate from the following locations:

From your...                      If you were...                  And resided there...
Country of nationality    At least 16 years of age    At least 6 months
Country of residence    At least 16 years of age    At least 6 months
Country of previous residence    At least 16 years of age    At least 1 year
Any country where you were arrested    Any age    For any timeframe
 

Note: Present and former residents of the United States do NOT need to submit any U.S. police certificates.

Important: Police certificates expire after one year, unless the certificate was issued from your country of previous residence and you have not returned there since the police certificate was issued.

請問 這是什麽東東？ 到哪申請？
謝謝！
