Police report

[anonymous daij]

Good day to you all!!
i am an MBA student who is currently living in china, but however i am about to complete my studies and i am leaving china in June to go back to my country. i am thinking of taking a police clearance before i go back to my country because i would love to use that police clearance for the dv lottery (well that is if i get selected for further processing.... i just want to be safe). i want to take the police clearance then stay in china for a few days after taking the police clearance. will it still be valid?? or my stay in china for a few days will make it void. please help me
