International Agreement visa explained, including eligibility, treaty-based work requirements, sponsorship rules, application process, duration limits, and UK immigration conditions under the Temporary Worker visa category.

The International Agreement visa is a UK immigration route within the Temporary Worker category of the points-based immigration system. It allows individuals to come to the United Kingdom to work in roles covered by international law or treaties between the UK and other countries or international organisations.
This visa is typically used for employees of foreign governments, international organisations, or individuals working under contracts governed by international agreements. It is a tightly controlled route designed for specific diplomatic, UK government, or treaty-based work rather than general employment.
The visa is governed under the UK Immigration Rules as part of the Temporary Work – International Agreement route.
Purpose of the International Agreement Visa
The International Agreement visa exists to enable the UK to meet its obligations under international treaties and agreements. It is used where work in the UK is permitted under:
- Diplomatic agreements between countries
- Treaties with international organisations
- Certain official government-to-government arrangements
- Contracts governed by international law frameworks
It ensures that individuals can lawfully carry out work in the UK that is required under international commitments while maintaining immigration control.
Legal Framework and Immigration Structure
The visa operates under the UK's points-based immigration system, specifically within the Temporary Worker routes.
Applicants must meet:
- Sponsorship requirements from a licensed UK organisation
- Eligibility under an international agreement
- A valid Certificate of Sponsorship (CoS)
- Salary and role requirements where applicable
- Suitability and immigration compliance checks
The Home Office assesses both the sponsoring organisation and the nature of the international agreement to ensure the role falls within permitted categories.

1. Employees of overseas governments or international organisations

Workers whose employment is governed by:
