I've posted in chat, but thought maybe somebody here might know...
A bit boring, but I can't seem to find the info online 
I am learning to drive and hold a provisional license, in order to supervise me the rules say the person accompanying me must be 21 or over and have held a full license for at least 3 years. DH ticks these boxes but his license is non-EU, non-exchangeable. Is it still okay? I can't find anything to say otherwise and his license is a full one, that he's held for 9 years.
The other issue now is that he's not yet taken his UK test. Rules say he has a year from becoming a UK resident before he can no longer use his license. I don't know if that means from the day we moved here, or the day he was granted legal residence. Our insurance is up for renewal in about 6 weeks, so at that point he will have been driving for a year here (2 weeks after arrival in the UK, 2 months before being legally resident). I'm at a total loss as to when he is no longer allowed to drive, and when he does, will he be able to supervise me? He will still have the other license, he just can't use it to drive here.
TIA!
