In the second of two encounters with some kind of financial service (a bank and a letting agency specifically), the fact that we have jobs and will be making apparently a good salary in Pounds has opened doors that might previously have been closed. I've been corresponding with a leasing agent trying to find a place in and around Camden Town, and after the initial "Hi, I'm an American!" we got down to business - and they would require six months rent up front. Tell them you're employed and you have a good salary, and suddenly you're taken far more seriously. Same with the bank; when they found out how much Elizabeth would be making each month, our options for bank accounts and credit cards multiplied threefold.
At least our hard work has paid off a little in this regard, because I couldn't imagine fucking around with some of this stuff not knowing about a job or making a pittance.
