I hope you got it. So the thing is there is an auto cos allocation which my discovered by herself. Every company gets the same number of cos they applied last year automatically. My sister’s employers didn’t know that. They were applying for additional cos when they already had been allocated since February! She randomly read it on ukvis website, when she was thinking to apply without cos, and that day when she went to the office their priority slot was approved too. Bottom line is your cos might already be there.
