Depending upon the level at which your husband is coming here, he can get a Green Card inside a year. If he is a Manager in a multinational company, his company can apply for his
GC in EB1 categaory. With this category, they will be able to circumvent some of the process and will get the
GC inside one year. You could start working here half way through it when he gets an EAD.
Cheers,
