1. 我是公民，母亲B2 签证第一次到美国，可以办绿卡吗？
-Yes.
2. 我的出生公证是2000 年办的，可以用吗？
-Yes.
3. 如果I 130 和485 同时递交的话，是不是收到收据就是合法等待了？
-Not need to get the receipt and as long as USCIS receives the I-485 application, they can stay in US legally (e.g. 3 to 4 days after mailing it out using Express).

-Two to three weeks, normally.
4. 如果我帮母亲填485 表，签名的地方是选哪一种呢？

b. through interpreter-You sign this part.
c. Preparer 签字-You. sign this part also.
