Ask an Immigration Solicitor. Get an Answer ASAP.
I am a solicitor.
Did you marry your husband lawfully in Nigeria?
Sorry, I am unable to call.
Your husband needs to apply for a dependant visa and he will need at least £285 support funds for the visa.

May I help further?
You may start the application right now if all the required documents and money are available. Yes, all documents need to be available.
All the best
You are welcome.
