I'm in a similar situation, this is all very useful information - thanks! Rather than creating a whole new topic I thought I might piggyback here, if cmatta86 doesn't mind.
My question:
Quite a few people here on the forum just haven't bothered changing their name in their passport and so have kept their passport and BRP in their maiden name, while using their married name for everything else.
I'm on ILR in the UK, and am eligible for citizenship. I'd like to change my name and apply for my UK citizenship & passport, but I'm not sure of the best order in which to do these things.
If I do the name change first, I'd imagine that I would have to have my ILR re-issued in the new name. That would then be a waste of time and money, because it would be redundant the moment that I got my UK citizenship.
On the other hand, getting my UK citizenship first and then immediately changing my name seems like it would need a lot of remedial form-filling as well.
Not to mention the US situation. If it's possible to just keep my original name in the US I wouldn't mind a bit, but I'm not sure whether or not that's possible.
Finally, I'm not sure if it matters, but my name change is not going to be marriage-related.
Any thoughts or advice gratefully received!
