Congratulations!
We decided to use my wife's maiden name on the application because we didnt want to introduce any additional variables. Namely that all of her work documentation was in her maiden name. My Visa vignette explicitly states my wife's name with maiden name, though we were planning that she'd change it as soon as I got there. How would a name change affect the validity of my visa/visa vignette? And if there is an issue, is there guidance for resolution? This cant be the first time this has happened :p
The visa can ONLY be issued in the name on her passport, and it must match her passport at all times. So, you had no choice with that - you had to use her maiden name.
If she wanted to change her name on her passport and visa, it really needed to be done before you applied for the spousal visa.
In order to change her name on her passport and visa after she has arrived in the U.K., she will need to apply for a new passport through the US Embassy in London (takes about 3-4 weeks), then she must change her name on her BRP Card (Visa) within 3 months, or she can be fined £1,000 and potentially have her visa cancelled.
In order to change her name on the BRP, she will have to apply to UKVI for a change of circumstances. This costs about £160 and takes about 2 months to be processed.
The other option is that she just uses her married name for other things in the UK, but keeps her passport and visa in her maiden name until just before she applies for her next visa in 2.5 years... that way she can change her name on her passport and then hey apply for the next visa in her new name without having to change her BRP Card.
