If the husband is Emirati, residency may be granted to the foreign widow or divorcee without children if the husband is Emirati and the residency is issued within 6 months of the date of death or divorce.
If the husband is foreign, the UAE government will allow a widow or divorced woman to get residency if she has custody of the kids within 6 months of her husband's death or divorce. She has to be in the UAE when the application is made, and her husband had to be the guarantor at the time. If she wants to sponsor the kids' residency under her own name, she needs to be their legal guardian.
