I emailed Delhi immigration number of times. They just have simple response that delay is due to COVID-19. Also send them lot of web forms for remedical that is done now and updated in my GCkey on April 20, 2021. Then again I sent them web form on April 28, 2021 requesting them to provide me visa outcome. Lot of students in my country are waiting for their visa from approximately a year or more. Some students are getting their results within 20 working days and some are waiting from year. It is totally unfair and disgusting situation.
It is definitely unfair, I was in that position too before. People who applied months after I did received their approval before I did.
What I did after I realized that they keep on replying the same generic thing to me was I made my emails more personal. I figured sending the same copy+pasted emails to them wasn't working so I made it more personal then told them about my situation (that I applied 8 months ago, etc.) I included all the scanned copies of the files I used for my application.
It's literally like making a new Letter of Intent because the situation when I applied was different compared to the situation months after. I took COVID into consideration in that letter. I think it really is important that they know you could fund yourself amid a pandemic.
Try to make your emails personable and try to include all the needed files in your document. Make the details bulleted, that's what worked for me. What also worked was putting "URGENT: etc etc" as the subject.
I
really hope this helps. I know it's taking too long, and I know how frustrating it could be, but the situation in your country might also be a factor (to which I'm also extremely sorry to hear about).
