Defined vs Undefined COS: Key Differences in UK Sponsorship Certificates

UK Immigration Blog

In the United Kingdom, the immigration system is complex and multifaceted, with various rules and regulations that both employers and employees must adhere to. One such aspect of this system is the Certificate of Sponsorship (COS), a critical document for employers who wish to hire non-European Economic Area (EEA) workers. The COS can be either defined or undefined, each with its own set of characteristics and implications. This article will delve into the key differences between a defined COS and an undefined COS, their processing times, and their implications for UK sponsorship certificates.

Understanding the Certificate of Sponsorship (COS)

The Certificate of Sponsorship (COS) is a virtual document with a unique reference number, which an employer, also known as a sponsor, assigns to a non-EEA worker. This document is not a physical certificate but an electronic record. The COS is a critical part of the UK’s points-based system for immigration, specifically for Tier 2 and Tier 5 visas.

Defined COS vs Undefined COS

There are two types of COS: defined and undefined. The type of COS issued depends on the type of job and the circumstances of the worker.

Defined COS

A defined COS, also known as a restricted COS, is used for workers outside the UK earning less than £159,600 per year. The defined COS is subject to a monthly cap, known as the COS cap. The defined COS processing time can vary, but it typically takes around one month.

Undefined COS

An undefined COS, also known as an unrestricted COS, is used for workers already in the UK or those earning more than £159,600 per year. There is no cap on the number of undefined COS that can be issued, and the processing time is typically quicker than that of a defined COS.

Key Differences Between Defined and Undefined COS

There are several key differences between a defined and undefined COS:

  • COS Cap: The defined COS is subject to a cap, while the undefined COS is not.
  • Processing Time: The defined COS processing time is typically longer than the undefined COS processing time.
  • Worker’s Location: The defined COS is used for workers outside the UK, while the undefined COS is used for workers already in the UK.
  • Salary: The defined COS is used for workers earning less than £159,600 per year, while the undefined COS is used for workers earning more than this amount.

Implications for UK Sponsorship Certificates

The type of COS issued has significant implications for UK sponsorship certificates. For instance, the defined COS cap can limit the number of non-EEA workers a company can hire in a given month. Additionally, the longer defined COS processing time can delay the hiring process.

Conclusion

Understanding the differences between a defined and undefined COS is crucial for employers looking to hire non-EEA workers. By understanding these differences, employers can better navigate the UK’s complex immigration system and ensure they comply with all rules and regulations.
