With this code, applicants are able to track the status of their queries. In queries submitted via SMS, the applicant is informed back again via SMS that the query has been received.

In such cases, we also inform our customers about the estimated date of response and how they can follow up their queries in the meantime. The queries are resolved by the qualified PR Officials of our Call Center. In case the situation entails a detailed investigation, the officials forward the queries to the experts of each concerned unit, who in turn handle the queries.
