Thanks feefad!!! If you need any advice, let me know
the main piece of do***entation they want to see is the ESOL/Life in the UK certificate. We applied on 31st March and got the passport back today! In between they did write to us asking how Mo was assessed before he enrolled on his ESOL course, so had to get back in touch with the college and get another letter from them. Incidentally, he's only passed ESOL 1 so far, they weren't looking for ESOL 3 which we initially thought...
Hubby is a bit stunned at the moment, the shock and excitement I think
