The link worked for me. I entered Payment Reference Number instead of IHS number.
I applied Tier-4 UK Visa on 31st July and opted for Priority service. Received an email on 1st August stating that the application has been submitted to an Entry Clearance Officer. It has been 14 working days since that email, no further updates yet.
However, found the link
https://contact-ukvi.homeoffice.gov.uk/ ... visastatus in this forum and checked the status. My application status is "Decided" and it was updated on 13th August 2017. It means a decision has been made and the page says that I would receive the decision within 10 working days. It must be noted that even if we choose Priority service, it could take more than 10 working days to arrive at a final decision, and also I am yet to receive the Passport.
It is a bit of a relief for me to know that a decision has been made but heart is still beating to know what the decision is.
