I may have mentioned her a couple of times, but please meet my friend, Jodi (>link to her blog here<). Jodi is Canadian and despite being over here for quite some time (and being the awesomest line manager ever in my first grown up job), the UK Border Agency (UKBA) have decided she is no longer eligible to live and work here in the UK. She has blogged a little about it and her progress (the first post is >here< outlining all of the details of the first letter). I have never had this problem personally, being from the UK and never adventuring to live or work beyond our pastures, but if you have, please head on over to her blog and comment all sorts of love and helpfulness.
If the Internet was designed for anything, it was probably to help one another.
