Hey Guys,
I have submitted the application in SINP EE on 1st January 2018 and paid the fee of $300. I saved the generated invoice in PDF format and also the status of the application is changed to "Application Received" with Application number being assigned to me. In "View my Correspondence" section, I am able to see an auto-generated message with the confirmation of application submitted and the attached "Received Application Letter.PDF" which states that the application is successfully submitted and will be reviewed.
Best Wishes,
R
Update: Just checked and have received the confirmation email from SINP. Somehow, it got landed in junk folder but now marked as safe
