G-28 问题, 恳请小白兔,Pjiang, Radiology 伸出援手, 谢谢!

我七月发485时,signed 过 G-28 (律师).现等待485结果期间,我想第一时间收到从USCIS来的邮件,所以拟再自己签一个G-28. 有几个问题,诚请各位大师帮助回答:

1. 在"I hereby enter my appearance as attorney for (or representative of)"下面,是否该填自己的信息?
2. 在接下来的 "Check Applicable Item(s) below:", 如有律师,应选(1.). 象我这种情况, 该选那一项呢?
3. 紧接着,有三个签名,是否都要签呢( a. SIGNATURE, b. (Name of Attorney or Representative), c. Signature of Person Consenting).

衷心谢谢各位的帮助!
