U r welcome
According to my knowledge if u had received correspondence letter then decision is already taken... They just need to deliver it to u.... Many of my friends who got correspondence letter called them and they atleast got to know that they r approved.... But in some cases it has gone other way around where file is still in process so actually there's no way to figure out what is the status of the file coz scenarios exist in both the cases.... I am too bewildered... U can call them and ask them provided u should be confirmed that ur file is processed at Canada and u have waited quite from a long time.... Ircc agents r very kind.. Professional and very helpful also.... I got my visa couple of days after calling them as they put a note on my file to speed up the process.... But in my case i called after 70 days and I was confirm that my file is in Edmonton.... U can call them once and confirm about it... I wish u best of luck... When I explain things to folks I write an essay itself so please don't mind for my long essay explaination lol
