Which documents do I have to present to the aliens (registration) authority for every extension or transfer?
If you want to extend your residence permit or want to have an unlimited residence permit (today: permanent residence permit) transferred into your new passport, the aliens (registration) authority will always need an up-to-date, i.e. not older than six months, biometric passport photo and your valid passport.
For a transfer, please also bring your old passport unless this passport was seized by your embassy and/or consulate.
Which other documents are required for the extension of your residence permit depends on the purpose of residence. The employees of the aliens (registration) authority (contact details on the right) will tell you which documents are required in your individual case.
