Because i was waiting from more then a year
Previously i lodged my file in January 2020 end.
Now i have to redo medical also because it was expired that's why i prefer to relodge my file.
Applied: Jan 2020 (Under SDS)
Biometric: 5th February
Biometrics & Medical was updated
Asked for new LOA in July
After that no update
Applied for GCMS notes on 28th December still waiting.
In my point of view
You should wait because there are many pending files in the pipeline & now 14 weeks is the official time for India for processing SDS files.
Cost is around 10-20 CAD
And waiting period is 30-45 days.
Usage is that you can get the entire report of the file. Sometimes it also mentioned that visa approved or eligibility passed.
