The security investigation in Turkish citizenship applications is an important administrative stage in the assessment of the applicant in terms of public order and national security. This process is an examination that is often unknown to the applicant but directly affects the outcome.
The security investigation is based on the applicant’s background, official records, statements and connections. At this stage, the administration assesses whether the person poses an obstacle in terms of national security or public order. This assessment often includes the opinions of different public institutions.
At this stage, the criminal history, address records, economic situation, residence patterns and the consistency of the statements in the file are important. In particular, contradictory statements or missing documents can have a negative impact.
The length of the security investigation may vary from file to file. Prolonged procedures do not always have a negative meaning; however, legal follow-up may be necessary to know at what stage the file is.
In case of a negative outcome of the investigation, a rejection decision may be made. In this case, the concreteness of the reason for rejection, the limits of the administration’s discretionary power and the lawfulness of the decision should be assessed.
Applicants are often not fully aware of the scope of the security investigation. However, this process is one of the most critical stages of the citizenship application. It is of great importance to prepare an honest, consistent and complete file.
As a result, the vetting process is one of the confidential but decisive stages of the application. Setting up the file correctly from the beginning reduces potential risks.
