Police clearance report for fiancee visa

Hi there,

I have a quick question about the police report requirement for the Fiancee Visa application.

It asks for a police clearance letter from each place you lived for the past 6 years - which for me is 7 places! 5 of these are in the US (I was in the US on a student visa, which is when and how I met my fiancee).

So my question: I am having trouble getting these clearance letters... 3 of the police departments have no idea what I'm asking for and the others are charging between $10 and $20 for this letter.

I was wondering if instead I can pay for one of those criminal background checks for the US and have that cover my entire stay in the states?

I can't find this information anywhere, but I assume this is because the majority of people applying to enter the states have not lived there for the previous 6 years. I currently live in the Netherlands and had no problem obtaining a report here.

Surely a US background check woul satisfy this requirement?

I'd appreciate any advice!!

Thank you, and good luck to everyone else on here
