Yes, there is still a chance. While the process can be unpredictable, there have been instances where individuals received their visas even after their number remained current for an extended period. It often depends on various factors including the specific visa category, the volume of applications, and the processing speed at your consulate or embassy.
If your number was current by September 2021, it would be advisable to follow up with the consulate or embassy handling your case and check for any updates. Keeping in touch with them can sometimes provide more clarity on your specific situation.
Good luck!
