Do be considered for a room in KaWo1 you need to apply in the applicant portal of the Studierendenwerk (STW) Aachen for a room in our dorm. You can find it here. The waiting time varies depending on lot of factors.
As soon as the allocation comitte is able to allocate rooms, it will screen the list of applicants according to the STWs allocation guidelines and contact suitable applicants. If you then accept as an applicant, you will receive an email from the STW after some time in which you should confirm your rental request. Once this has been done, you will receive another email ~4 weeks or as soon as possible before the desired move-in date with the specific room number and the further procedure regarding the deposit and signing of the tenancy agreement.
