飞出国： 在德国，居留许可分为短期居留许可和长期居留许可两种类型。
短期居留是以短期在德国居留为目的签证，一般有最长居留时间的限制。比如，交流项目居留（一般不超过12个月），留学居留(最长10年)，劳务工作居留（最长4年），语言学习居留（最长2年），互换生居留（最长2年）等。
长期居留是以长期在德国生活为目的的居留，没有最长居留时间的限制。例如，欧盟蓝卡签证，法人签证，以及他们配偶和16岁或18岁以下子女的家庭团聚类居留等。每次签发的有效期一般为1-3年，最长一次签发不超过5年。居留到期后，可以延续有效期，满足一定条件后可以申请永久居留。
永久居留又称定居居留，是长期居留的一种。指的是持有长期居留的申请人在满足一定条件后，可以申请取消长期居留卡上的有效期，居留卡上会标注居留有效期为无限期，即可永久在德国居留。

granting such a temporary residence permit is not precluded by reasons of public safety or order, according due consideration to the severity or the nature of the breach of public safety or order or the danger emanating from the foreigner, with due regard to the duration of the foreigner’s stay to date and the existence of ties in the federal territory,
