What is the


ECAA – European Community Association Agreement with Turkey (Ankara Agreement)
The European Community Association Agreement (ECAA) with Turkey allows Turkish nationals to enter the UK and establish themselves as self-employed businesspeople, i.e. run their own businesses.

Article 13 of the ECAA (also known as the Ankara Agreement) removed restrictions relating to the freedom of establishment, allowing Turkish nationals to establish themselves and provide a service to others. Article 41 of the Additional Protocol to the Turkish ECAA, known as the “standstill clause”,is a supplement to Article 13 of the ECAA. This clause allows Turkish nationals wanting to enter the UK or who are seeking leave to have their applications evaluated under the domestic rules that were in force when the UK joined the EU in 1973. The result of this is that all applications are treated the same and identical rules are applied for all applications.
