I am currently living abroad. How do i get some sort of a police report/criminal report,?

Every country has its own federal law enforcement agency that does such background checks.

In the absence of some more specific detail about precisely what you want or from whom, or why, I can only suggest asking at your nation's nearest consulate.

If you’re at least 16 years old, you must submit a police clearance certificate from each of the following countries (except the United States), whether or not you’ve ever been arrested there:

Your country of nationality if you’ve lived there for at least six months at any time in your life

Your country of residence if it’s different from your country of nationality and if you’ve lived there for at least six months

Any country if you’ve lived there for at least 12 months and were at least 16 years old at the time

You also must submit a police clearance certificate from any locality in the world (except in the United States) where you’ve been arrested for any reason, at any age, and regardless of how long you lived there.

I am unable to fly to the US. i need some sort of a criminal background/police report for some document processing. Are there (online) agencies out there that provide these kind of services? Thanks
