I-485表格几问

问题比较幼稚, VERY VERY APPRECIATE YOUR HELP. 我以前是F1, 现在EB1B刚交,收到RECEIPT, 所以准备早点把I-485交上去


==========================
(1) Part one: Inofrmation about you:

什么是 A# 啊? 我看 我的 SSN (SOCIAL SECUITY CARD) 上有A #, 是那个吗?






===========================
(2) Part two: application type

我的EB1B刚交,收到RECEIPT, 所以准备早点把I-485交上去.
我应该SELECT A 还是 H?

A: an immigrant petition giving me an immediately available immigrant visa
number has been approved.

H: Other basis of eligibility.





=================================
(3) Part 3. Processing information.
我到哪儿去找
(3a) Nonimmigrant Visa Number;
(3b) Consulate Where Visa Was Issued
(3c) Date Visa Was Issued

护照上好象没有 (有也只是F1).
