Is it permissible for a woman who has been granted a revocable divorce to travel during her waiting period (iddah) to renew her residency in her family's country, especially if her former husband has given her permission to do so, bearing in mind that there is concern that her husband may not take her back, and that travel is essential for renewing her residency?

The basic principle is that a woman in her 'iddah (definition) (waiting period) must remain in the marital home and not leave except for a daytime need, or for an urgent necessity at night, provided she spends the night in her home. If refraining from travel does not result in harm, or if postponement is possible, then travel is not permissible. However, if refraining from it would result in harm, she is permitted to travel out of necessity. Reconciling differences is better, especially when children are involved, as divorce is fundamentally prohibited unless there is an overriding reason that permits it.
