UPDATE:
So I have been checking my status on this link impatiently every few hours throughout the day:
https://contact-ukvi.homeoffice.gov.uk/ ... visastatus
Just to let you know, the way this link works is it will only show you your application status once it is decided. If you try to input your GWF code and the application is still under process, it will show code unrecognized. It was showing code unrecognized every time I checked, until today.
I checked right now, and it is updated showing the decision has been decided. (and it might take upto 10 working days to deliver).
I did not receive any call for a second interview. So I guess the not straightforward e-mail was just to justify the extra time they took. Now I just have to wait for my passport, which will probably by quite nerve-wrecking
Timeline: (Location: Doha, Qatar)
July 06th, 2017 - Filled Online Application
July 09th, 2017 - Bio-metrics and Document Scanning
July 18th, 2017 - E-mail that application is received and ECO has been assigned
Aug 15th, 2017 - E-mail that "unfortunately, your application has not been straightforward"
Aug 16th, 2017 - Application Status : Decided (shows decision made on 14th Aug)
Hope this helps
