For example i send my applicatiom mar 2010
When i expect MR?
Thanks
By April/May 2012 you may get MR even though no body can precisely predict.
Speed of your case process depends on simplicity/complexicity of your application case.
Also you have not mentioned your time lines. like RBVO, AOR2, Inprocess...
During Inprocess, after your documents/background checks, you will get your MR.
