Umrah is neither imperative (Fard) nor obligatory (wajib), but performing Umrah once in a life time is a Sunna. However, once or more than once, whenever it is performed, it fetches great rewards.
1- "The people who come to perform Hajj or Umrah are the guests of Allah because they visit His House on His Call; therefore, Allah grants them what they ask for"
2- "One Umrah becomes an atonement for the sins committed up to the next Umrah"
"The performance of `Umrah is expiation for the sins committed between it and the previous ones. And the reward for Hajj Mabrur (pilgrimage accepted by Allah) is nothing but Paradise." (Sahih Al-Bukhari, Vol. 3, Book 27, Hadith no. 1)
