The current status of my paper is "Under Review." I would like to know how long it will take for the review process to complete. How long should I wait before sending an inquiry to the editor? Submission “Submission Being Processed” – 31/06/2017: The manuscript is submitted and an e-mail is sent to the corresponding author with EES login details. The manuscript is assigned to an editor by the journal office staff. “With Editor” – 07/08/2017 (estimated) : Presumably an editor makes sure the thing is worthy of being sent out for review and identifies appropriate reviewers. “Under Review” – 11/10/2017 : The peer review process starts. "Under Review” – 20/10/2017 : The peer review process starts. Again! :( "Under Review" - 30/01/2018 : The peer review process starts. Again!! :( "Under Editor Evaluation" - 18/05/2018 ? Today 2017/12/19 over 2 months, my paper's status remained same "Under Review". I wanna see next statu
