How long will it take to get a visa so he can work? We haven't filed for anything yet. Can someone who is fimiliar with immigration laws please respond.
By the way my husband has a ITIN

Nobody can give you the correct answer from insufficient info given.

Tell the whole story in details.. how did you enter US? What kind of visa? Is it now expired? Are you married to US citizen? Do you have employer that is willing to hire you, and sponsor visa for you? etc.
