Thanks for the replies. My wife was in the UK with me for 8 years on a spouse settlement visa but she was unable to pass LITUK - she studied hard and took it twice but couldn't do it. So she never had ILR. So I got totally fed up with the UK visa system and the ludicrous expense of it and we emigrated to Thailand 2 years ago just when covid hit. However, despite covid (and actually because of it in some respects) this was a good move financially and at the moment we have no plans to return to the UK. We might in the future depending on circumstances so I was just wondering what her status would be if we returned for settlement.
From what you guys have kindly told me, there are rules for people returning with ILR - 2 year max out of the UK etc. I was aware of that. However, there doesn't seem to be anything in black and white to cover our situation. I suspect that she would have to complete another 5 years before being considered for ILR regardless of how old she is.
I would imagine that this situation has occurred in the past so it would be useful to hear from anyone with practical knowledge of it. Cheers.
