Just thought this might help others:
My wife and I live together in the US and are moving back to London shortly. I am applying for a settlement visa. Instead of sending her passport, I am sending a certified copy. I spent 3-4 hours trying to find where to get such a copy. Most of the advice in this thread is how to do it if the UK sponsor is living in the UK.
Since we are both in the States I found out that my bank, US BANK, will make a certified copy of every page in her passport, FOR FREE, because we are both US Bank customers.
I was refused at Fedex Kinkos because they wouldn't certify a copy of a Passport, and although the UPS store would do it, they only had a notary at one location, and he wasn't in until tomorrow afternoon. My biometrics is tomorrow, and I plan to post everything straight away, so I wanted this finished today.
