It clearly says
For the country where you currently live
The police certificate for the country where you currently live:
For any other country
- must be issued no more than 6 months before the date you submit your application
- must not be expired
For any other country, the police certificate must be issued after the last time you stayed there for 6 months or more in a row.
Some countries put expiry dates on their police certificates. If you have a police certificate that expired, include it. We’ll accept it if:
An officer may ask for a new one later on.
- it was issued after the last time you stayed there for 6 months or more in a row
- it is not for the country where you currently live
Dont worry if you don't have expiry date on your PCC and you haven't visit that country you should be all set
Awesome! Thanks
