Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Can you afford to pay for a Uk Course for him?
If you can afford for him to do a course in the Uk then yes it would be best if he comes on a Student Visa
He can come for 11 months
and assuming that his English is then acceptable he can then apply to stay as your partner.
Please ask if you need further details
It is not hard - they will need to feel certain that he will return at the end but it is a reasonable step to take
Whilst you cannot extend the Visa he can then apply for a spouse visa
He can apply to remain with you if he has a Student Visa - there is no bar on doing so - more details here
He can apply for a Student Visa if he is already here
I assumed that he would live with you wherever you are staying
That is all - you just need to add evidence that you will be in the UK
A note of the address you will be living at - a copy of any job offer - whatever you have that shows you will be in the UK - or even the address of the relative who will put you up.
