請教8老師關於父母申綠卡和填表問題. 非常感謝！
I-130
1. I94 number, 倒數第二位是字母，pdf表不讓填怎麽辦？可以打印出來以後手填嗎？-Yes.
I-485就可以填字母。
2. 46d, I94上的experiation date是5/20/2020，已過期，4月遞交延期現在還pending（原來沒打算深綠卡，現在眼看著延期批不下來，老太太腿腳不好又回不去才申綠卡）。請問 expiration date還填5/20/2020對嗎？-Yes.
然後在part 9解釋延期 I539 extension pending?-Not need. It will not affect your parents I-485 approval, anyway.
3. 如果這幾天延期批準了i94就應該算是experiation11/20/2020對嗎？-Yes, the new I-94 expirationd date if it is approved before the I-485 filing.
4. 如果11/20之前隻提交I130，11/20之後也可以算合法拘留嗎？還是11/20之前必須也提交485？-They had better file I-485 together with the I-130. Thus, they can legally stay no matter whether the B2 extenson is approved or not.
5. 60b USCIS office 是寫我們local城市的，-Yes, fill the USCIS Field Office which covers your area.還是寫我應該遞交的center （chicago)?
6. 父母離婚，是否就提供離婚證明公證就好了？結婚證明不需要了吧？-Need to provide both marriage and divorce certificates.
7. I485，part 1 ,19讓填nonimmigration visa number from this passport. 可是有效簽證在過期的passport上，還可以填這裏嗎？-Yes, put the visa number which they used to enter US for the last entry.
