F1申請EB2 - 移民

(代PO)

如果某A剛入境, 要以F1 STEM OPT身份申請EB2綠卡,
會遇到一個90 days rule, 想請問這個90 days rule實際運作方式.

- I-140有需要在入境90天後才能送嗎？
律師說任何時間都可以送, 因為這個是公司申請的, 某A不知情,
可是I-140必須要繳交有某A簽名的PERM, 聽起來有抵觸.

- I-485律師說肯定得入境90天後送, 這個對嗎？
如果是的話, 假設一過90天就馬上送I-485 (如第91天), 會不會有問題？
還是得拉長時間, 如120天？
因為審查資料的準備需要時間, 附上的資料有的會寫申請日期,
資料申請日期(或體檢日期)可能是在入境90天內或之前.

- The Foreign Affairs Manual at 9 FAM 302.9-4(B)(3)是這樣說的
Undertaking any other activity for which a change of status (NIV to NIV) or
an adjustment of status (NIV to IV) would be required, without the benefit of
such a change or adjustment. Simply filing for a change of status or
adjustment of status is not in itself sufficient to support a presumption of
misrepresentation under the 90-day rule; the individual must also engage in
conduct inconsistent with authorized status without the benefit of such a
change of status. Moreover, if an individual engages in the activities for
which he/she was admitted, such as to study on a F1 visa, but also engages in
unauthorized work without seeking an employment authorization document (EAD),
then that is insufficient to justify a presumption of a misrepresentation.
我的理解是,
某A必須入境90天內AOS或從事綠卡才能做的事 "instead of" 入境visa允許的事才算違規.
如果某A入境確實是為了進行STEM OPT的事項, 在入境90天內送I-485還會違規嗎？

- 有人說The Foreign Affairs Manual對USCIS沒有約束力, 所以I-485一入境就送沒問
題, 不需要管90 days rule. 這個說法對嗎？

- 假設I-140要走PP加上I-485要等90天的情況下, 是不是乾脆等90天, 140跟485一起交就
好, 而不是先交140？還是先交140有什麼好處呢？

- 在已有PERM的情況下, 剛入境要申請綠卡, 除了90 days rule外,
還有什麼要注意的嗎？

抱歉問題有點多, 想一次問清楚, 謝謝!
