1. 關於N／A和 None
究竟什麽情況寫N／A或是留空白呢？很糊塗
比如middle name， 曾用名，USCIS online account number等等
-- Middle name: "留空白"
-- 曾用名: N/A 或者 "留空白"
-- USCIS online account number: N/A
2.Part 5中 ＃1 provide most recent residence and list every location where you have lived during the last five years.
這五年中我回國兩趟，前後總共待了共7（4+3）個月（其中有6個月是在收到綠卡後，我是第一次回國後人在國內的時候綠卡批準的），也需要寫地址嗎？
--Yes
3. 請問Part 12 的
9 A. Have you ever been a member of, involved in, or in any way associated with, any organization, association, fund, foundation, party, club, society, or similar group in the US or in any other location in the world?選Yes後，記不清什麽時候開始不交黨費了，隨便寫個時間也可以吧？
-- Tell the truth. 不記的就填大約年和月
10 Have you ever been a member of, or in any way associated with A. The Communist Party?
是不是9，10隻要附一份statement 解釋因為長時間沒有交黨費相當於退黨就可以了？
-- Yes, one statement for Communist Party. People ususally say for living, promotion, better job, etc
