Does the 'iddah (waiting period) apply to a non-Muslim woman whose marriage contract has been annulled, and is it permissible for her to embrace Islam and marry a Muslim after the annulment without observing the 'iddah?

A non-Muslim divorcee is required to observe the waiting period (iddah (definition)) just like a Muslim woman. Her waiting period is three menstrual cycles if she is of menstruating age. Her iddah begins from the date the judge issues the ruling of annulment (faskh (definition)), and she is not permitted to marry before the expiration of her iddah.
