1. 如果the date of service 是 March 1， given 30 calendar days after service of the decision, 最后的filing date 是 March 30 还是 March 31？(postage date?)
2. I-290B 表格有三个选相：
D.I am filing a motion to reopen a decision. My brief and/or additonal
evidence is attached.
E.I am filling a motion to reconsider a decision. My brief is attached.
F.I am filling a motion to reopen and a motion to reconsider a decision.
My brief and/or additional evidence is attached.
这几个选相有啥区别？选哪个好？
3. 在 appeal denial 之后的 motion to reconsider 是 file 给 AAO 还是 field office?
4. motion to reopen 与 motion to reconsider 有区别吗？
万分感谢您的帮助！
