What are the rulings regarding the waiting period (iddah) for a woman divorced in absentia, in terms of its commencement, its duration (one menstrual cycle or three menstrual cycles), and the possibility of her leaving the house for work, visiting relatives and friends, and attending family occasions such as weddings?

The 'iddah (waiting period) for divorce begins from the time the final divorce decree is issued by the court. It is three menstrual cycles for a woman who menstruates. The woman observing 'iddah is permitted to go out for work during the day, while it is preferable for her not to go out to visit relatives and friends or attend social gatherings. She should not go out at night except for necessity.
