Regarding police certificates, it says you should submit one for every country you lived in since 18. For country specifics, my take was that if it says no additional requirements that is in addition to already expected police cert. This is my third time going through immigration process (other countries), it was always a must to submit in my experience. Just make sure you add them all (translated by approved translator if needed) and you'll be fine, this is just a time delay. You can do it, good luckYes for some reason they did not accept the marriage certificate, also they wanted a police certificate.
I wasnt really satisfied with the reasons
But I Guess thats what they want
