The Ministry of Hajj and Umrah has said that those dates cannot be changed after booking for Makkah Umrah. However, the ministry said that the permit could be revoked by the applicants through the Umrah application. The permit must be revoked six hours prior to the time of entry.
Permission should be sought through Tawakkalna and Ihtamarna apps. At present, one only has to seek permission to perform Umrah in the Masjid al-Haram.
