Thank you for your enquiry.
Your husband's Tier 2 visa is still valid and therefore he is able to remain in the UK until July 2018. The standard letter you received relates to the previous application for ILR which was refused.
Applying for ILR earlier than he should have does not invalidate his previous visa if the new application was a refusal and still in date.
Yes his status remains as before and he can continue to work. Please rate.
