It took EMGS 14 days in my case to send my E-Val Extension to the Immigration for approval (Applied on 27th September and Sent to Immigration on 11th October). However, once it reaches the immigration, EMGS says that they have no control over how long it takes. The time immigration takes to accept our application is not fixed and can apparently take upto a month
We are unable to provide you with an exact time-frame for the completion of theVAL extension application process as there are multiple levels of processing involved. Please note that your documents are ready to be submitted to Immigration Department. The decision to issue extension at the discretion of Immigration Deaprtment.
