my usc husband got incarcerater 3 weeks before the aos interview. what should i do? and what would be the outcome of such situation?

Perhaps the most proactive thing that you can do is to go to the immigration office where the adjustment of status interview is scheduled and ask to speak to a supervisor. There is a chance that the interview can be rescheduled if your husband will be released soon, or accommodations can be made to interview him and you either in person at the place that he is incarcerated, or arranging to interview him by remote camera.
