You can apply for a transfer block from the Central Register of Foreigners in writing or in person:

If you apply for the transmission block in person:

• Find out from your local immigration office what documents you need. If necessary, make an appointment.
• At your appointment, a member of staff will listen to you to find out the reasons for your request. A decision will then be made on your application.
• You will then receive a written decision. If your application is approved, the transfer block will apply immediately.

If you apply for the transfer block in writing:

• Contact your local immigration office to find out which application form and other documents you need. If there is no application form, an informal signed application is sufficient.
• Send your application and the required documents to your foreigners authority, the Central Register of Foreigners or the branch office of the Federal Office for Migration and Refugees responsible for processing your asylum application.
• After your application and documents have been checked, you will receive a written decision. If your application is approved, the transmission block will apply immediately.

Please note: Data transmission blocks can also be saved ex officio if there are interests worthy of protection or an overriding public interest. If a transfer block has been stored in the register ex officio, you as the data subject will be informed by the body that decided to store the data.
