Since we'll now be considered not straightforward for any future application, can we expect another 69BD wait for a spouse visa app? Or is February a better time and it would likely be shorter?
It's unlikely to take that long unless you end up stuck in a summer backlog again.
February time is likely to be much faster... 'normal' processing times (when there's no backlog) are about 1-2 weeks for priority applications and 2-4 weeks for non-priority.
With a previous refusal, you could expect it to take maybe 1-2 weeks longer than 'normal'... so maybe 2-4 weeks priority and 3-6 weeks non-priority.
Would it be useful to do priority, or not?
I don't relish all this waiting, but I just don't see how we could make it work now.
If you can afford priority, I would go for it.
I know they don't recommend using priority if you have a previous refusal, but that's just because they can't guarantee a fast decision and don't want people complaining that it's taking too long.
However, by paying for priority, you're still getting your application opened and looked at quicker than non-priority, so in that sense, it's probably worth it.
