Frequently Asked Questions
What is the difference between defined and undefined CoS?
Defined CoS are for Skilled Worker applicants applying from outside the UK; undefined CoS cover most in-country applications. We will advise which applies.
What if we choose the wrong occupation code?
Incorrect codes can lead to refusal and compliance scrutiny. We verify codes and salary thresholds before assignment.
