急！我要申请续ID了有几个问题希望大家帮忙

1.银行户口要保证有多少钱，9000欧？需要维持多久呢？
2.保险过期后，ID已经在申请中，这样是否不会i影响？
3.还有所谓的An original extract 是什么 说是from GBA demonstrating your resdential address.

希望大家 帮忙解答一下 多谢

To answer your 3rd question: that´s the document you need to get from the cityhall where you registered yourself. You can get it immediately, the document costs around 10euro.
