Ask an Immigration Solicitor. Get an Answer ASAP.
The financial requirement needs to be met by you as the British sponsor and not your husband I am afraid.
Yes on the second stage of the application both the applicant and sponsor can combine incomes. So if you have sufficient income then there is no need to use your husband income if this will cause an issue. But generally the income should be from the sponsor
In order to understand your circumstances we needed to know why you were insisting on your husband's income. I cannot help you without knowing the full context.
Give me a minute to read the context you have now provided.
When does his visa expire?
It is not pretty outrageous at all as the rule is clear and you would have been made aware of this before now. The timing for your husband going self employed was wrong which now has a knock on effect on his visa due date. Due consideration was not given for whatever reasons so you really cant begin to blame the rules. 31 December 2017 is last minute for you and your husband to begin considering his immigration requirements. You cannot use cash savings if you havent had cash savings for at least 6 months. It is really a bit too late now to plan. All he can do is present all the necessary documents to show his self employment income and previous salaried income. If application is refused he should appeal. Otherwise a bit too late.
Yes that is correct not to submit an application 28 days before BUT this does not preclude planning against an application. Yes but you have come too late to justanswer and too late for face to face legal advice.
I cannot make assumptions about any case until I have had the full context. Your initial context was missing a vital fact, which is you being the sponsor was unemployed and instead of looking at ways the law would support your case rather than suggesting the law as being outrageous. Your MP cannot provide you with any useful legal material on your case you should instead visit a face to face solicitor to make this application for you who would be prepared to challenge in an appeal should it become necessary. Good luck.
Yes everyone is entitled to their own opinion on the laws of the land but unless they are legally trained and qualified their opinion is uninformed I am afraid.
Dont worry I will end it from there. Good luck
