Simka is exhibiting strange behavior, and this behavior is quite untimely in that she keeps cancelling appointments with immigration and she's likely to be deported. Eventually, her behavior is diagnosed as PMS and she feels well enough, at least knowing what her problem is, to go through with her immigration appointment. After some difficulty, Latka & Simka convince immigration that theirs is a real marriage and Simka is awarded a green card. (thetvdb.com)
