Hi zimba,
Op breached the condition of stay in 2011, but that came to the attention of ukvi only in 2013, doesn't that mean he can only apply set lr successfully in 2023 ( after 10 year lapse from when ukvi foundhis breach). 10 years after breach was found by ukvi rather than the past date when breach happened- i saw this guidance on naturalisation. Or this past breach rule is different for set lr compared to naturalisation.
I can't seem to find any guidance regarding such situation for set lr.
