Do I need to provide a police certificate when applying for permanent residence?
Yes.
How and where do I obtain one?
If you live in Jordan
Police certificates can be obtained at the General Intelligence Department/Abdali in Amman. You must ask for the police certificate form for travel abroad. You must present two passport photographs, a copy of your passport and fee stamps.

You can apply for a police certificate through any Jordanian embassy abroad by presenting two passport photographs, a copy of your passport and fee stamps.
