PRACTICAL GUIDE ON NATIONALITY Special passports or travel documents (e.g. a stateless passport) delivered by the competent authorities, based on the result of the statelessness determination procedure, have therefore similar probative value as national passports. (b) Data related to travel to the Schengen area Information provided in visa applications submitted by the applicant or their family members to the country of asylum or other countries, in particular through the Visa Information System, can be considered relevant evidence. The Visa Information System records can shed light on the nationality and travel documents that the applicant possesses. The Schengen Information System provides information on public security issues related to the applicant, connection to criminal proceedings and use of falsified documents. It can also contain mentions of nationality and documentary evidence in this regard. (c) Language analysis, assessment or indication Language analysis does not establish the country of nationality of the applicant but may give indications of the place (or one of the places) the applicant has socialised by residing there for a longer period. Conversely, an applicant holding a specific nationality may not be able to speak their national language or may speak it with difficulty, for example, if they have lived abroad for a long period. There is a whole range of possible language assessments that rank from formal scientific processes to more informal procedures. If you plan to use any of these tools, exercise great care when assessing the credibility of an applicant’s country of nationality or formal habitual residence ( 86).
