Husband worked in UK for 7 yrs and wife has worked here about 5. Wife is on dependent visa. Husband got seriously ill and died recently. Is wife allowed to still stay in UK? What should she do to be able to stay? Can she apply for permanent residence? Husband is buried to UK and wife would like to stay here to be close to grave.

Please help me with this as this person is a good friend of mine and needs help with this.

Her legal status ended by the time of death of her husband. IF she wants to stay in UK, she may switch to employment visa, or apply for other types of non-immigration visa. She is not qualified for a permanent residence.
