Here are a few links to a blog on the National Air Transportation Association website. They are aimed at the aviation industry, but some of the general information about fingerprinting is relevant to everyone.

If you need translation services, I highly recommend Pascale Rigaud.  Pascale is not based in Paris, but can do certified translations of all your documents by mail and/or email.  She has been very responsive and reliable, with rates that are quite reasonable.

At present, the FBI is taking about 12-14 weeks to process fingerprints.  If you are a U.S. citizen, you have the option of using one of the FBI-approved channelers to process your fingerprints.  These agencies will scan your fingerprint cards and submit them to the FBI in a digitised format.  By using their service, you should expect to have your background check completed within 10 days to two weeks.  You will find a list of approved channelers on the FBI website.
For up-to-date information, please have a look at:

For Canadian background checks, you should be aware that the RCMP no longer accept paper forms.  You must send the forms to an approved agency in Canada.  They will scan them and submit them in a digitised format to the RCMP.  There is a list of approved agencies on the RCMP website.
