I sponsored my wife in Pakistan on Feb. 2016. Her application was forwarded to LVO after my approval as a sponsor. She was interviewed on May 2017 in Islamabad , Pakistan. Visa Officer asked to send some more documents like divorce notices given to my wife by her ex. and death certificate of my previous wife. I sent and theses documents were received by LVO on 25 june, 2017. since then I am waiting and haven't received any response. Application status says" We are reviewing eligibility" Should I be worried? and how long it will take to get the decision?
