Documents Required for Certificate of Sponsorship in the UK


Understanding the important documents required for getting a Certificate of Sponsorship (CoS) in the UK is key, given the constantly evolving nature of immigration and visa processes. A CoS is frequently the first stage in your trip, regardless of whether you intend to work, study, or join family in the UK. We’ll go into the details of the application procedure in this comprehensive tutorial, outlining the paperwork you’ll need to get the crucial COS.

What is a Certificate of Sponsorship (CoS)?

Let’s define a Certificate of Sponsorship (CoS) before moving on to the necessary paperwork. A CoS is essentially a digital document given to anyone who wants to live, work, or study in the UK by a licensed UK sponsor, who is typically a workplace or educational institution. This document provides important details about the sponsored person, the job or program of study, and the sponsoring organization.

The Significance of a CoS

The COS is a crucial component of the application process for numerous types of visas, including but not limited to:

Tier 2 (General) Work Visa

A CoS from a UK employer is necessary for persons seeking employment in the UK under this category of visa.

Tier 4 (Student) Visa

Students who want to continue their studies in the UK must obtain a CoS from the university or college of their choice.

Family Reunification

When reuniting with family members in the UK, a CoS may be necessary, depending on the circumstances.

Document Checklist for a Certificate of Sponsorship

Now, let’s get into the nitty-gritty of the documents you’ll need to obtain that all-important COS:

1. Job Offer Letter (for Work Visas)

A formal job offer letter from your sponsoring UK business is essential for Tier 2 (general) work visas. What should be in this letter:

  • Job title and description
  • Salary details
  • Commencement date

Ensure that the job offer meets the minimum skill and salary requirements for your chosen visa category.

2. Proof of Sponsorship License

Your employer in the UK must be in possession of a current Sponsorship License from UK Visas and Immigration (UKVI). Give proof of this important license.

3. Resident Labor Market Test (if applicable)

You must show documentation proving compliance with the requirements of the Resident Labour Market Test (RLMT) if your job opening was advertised in the UK’s resident labor market.

A CoS from your educational institution is necessary for Tier 4 (student) visa applicants. This CoS will include information about your course of study, related costs, and your duties as a student.

5. Financial Documents

As a visitor in the UK, you must demonstrate that you have the means to support yourself and any dependents you may have. Typically, one must provide financial records, bank statements, or other supporting data to prove their financial soundness.

6. Passport and Immigration History

Make sure your passport is up to date and has at least one blank page available for the visa stamp. Include previous passports, if applicable, to demonstrate your history of immigration and travel.

7. Tuberculosis Test Results

You could be required to present evidence of a tuberculosis (TB) test, depending on your visa category and place of residence.

8. Criminal Record Certificate

Include a police clearance or criminal record certificate from your home country or from any other nation where you have lived.

9. Maintenance Funds

In accordance with the requirements of your particular visa category, prove that you have enough money to meet your living expenses in the UK.
