DH and I did our biometrics today and had planned to have the visa photos taken, too. But it turns out that's easier said than done. Every place we tried (in person a couple of times), it was quite clear from talking to them that they were totally unfamiliar with the UK visa specifications: light grey or cream background, 45mm height X 35mm width, etc.
We even printed out the 12 specs to be sure. No one's camera equipment was set up for this.
A few of them just shrugged and others insisted that the standard 2inch X 2 inch photo would be acceptable, which we know is not so.
So, for all you former Dallas, TX area visa holders, where exactly did you have this done? (I tried searching the forum but can't find any suggestions.) Now that we've had biometrics done, the clock is ticking and am now quite anxious.
