关于留学生到底能否购买德铁通票的问题 German

官网的说明是：Please note:

This offer only applies for people with permanent residence outside Europe, Turkey and the Russian Federation. If you are European and live outside Europe you must have left more than 6 months ago (the stamp in your passport is decisive).


但是permanent residence是指永久居留，我们留学生拿的并不是永久居留啊，只是一年有效的要一年一换的。这也不能购买么？


而且他们看日期，是看我居留生效的日期，还是看我入境的日期？ 我中途如果有离开欧盟区再回来，怎么算？


谢谢各位了，因为有点赶，来不及买interrail了~..
