In our experience, visa application times for some countries can be tight to make it for the beginning of term. If you suspect this may be the case, keep in mind that the January selection (>2 months) leaves less time than the May one (>4 months). The only thing that you can do, is prepare as well as possible. Know all the steps of the procedure beforehand, book your appointments early, and have all the necessary documents ready. Some steps can be taken in parallel.
In some countries you need to prepare for visa application in parallel or even before the application to our programme (e.g. APS system). Please note, that application to our programme does NOT guarantee you admission. Accordingly, you might need to pay fees for the preparation of the application, but ultimately still be rejected or not offered a place.
Neither the MSc Biochemistry, nor other offices of the University of Tübingen can influence your visa process. The names of admitted applicants are forwarded to the APS authorities for priorisation. Whether you are priorised or not, is outside our control.
