回复：每次遇到问题都要到这里来.......现在等, 请Pjiang,小白兔等高人指点

1)申请EAD延期是不是最好在原EAD过期之前申请比较好??
- so as to avoid USCIS' stupidity
if you renew EAD on 3/24/08 which was expired on 3/24/07, what if you receive a new EAD w/ validity of 3/25/07 - 3/24/08?

2)还是说即使EAD过期了, 你也可以在任何时间申请延期?
- Correct

3)如果过期以后申请延期, 对延期申请有影响吗? 这时候还能叫延期吗?还是叫从新申请一个新的EAD?
- I would not choose "Renewal"

4)到底寄到哪个具体地址呢???
