The duration of the residence permit is always printed on the permit. If you have an electronic residence permit, you will find this information directly under your name in the "Valid until" section. If you wish to stay in Germany for longer than the registered period of validity, you must apply for an extension of your residence permit.

A residence permit is accompanied by ancillary provisions, which may also include an invalidation provision, e.g. "Expires within four weeks after termination of employment". In this case, should your employment be terminated, your title automatically expires after four weeks without further notice or order by the immigration authorities. Here, too, you must immediately submit a new application if you wish to continue your stay in Germany.

A residence permit is withdrawn by the immigration authorities if it was not granted in conformity with the law. If this happens, you will be heard by the immigration authorities before the withdrawal actually takes place by administrative act.

The immigration authorities revoke a residence permit by administrative act if there have been subsequent changes to the facts of the case. Here, too, you will first be heard beforehand and will then receive an administrative decision of revocation.

If a foreigner's residence endangers public security and order, the free and democratic order or other considerable interests of the Federal Republic of Germany, he or she will be expelled. The previous residence permit thus expires.

• upon announcement of a deportation order pursuant to Section 58a:
  If a foreigner poses a particular or a terrorist threat to the security of the Federal Republic of Germany, deportation can be pronounced without prior notice of expulsion.

If you leave Germany for more than six months, a residence permit expires automatically, unless the immigration authorities has agreed to an extension of the re-entry period (e.g. if you plan to stay in order to care of a sick relative for eight months and subsequently return to Germany for the long term). Please submit an informal written application for examination stating the reasons for the more than six-month absence and the intended date of return.
