大學好像HR說，你實際目前還不算有綠卡，發工資可能有問題，上個月下旬入職，也沒拿到工資，保險報上去了，也沒消息了，到現在都不知道這個月工資是否會發？這種情況是需要移民局辦什麽證明嗎？
-Your HR is wrong. You has been a green card holder from the date you entered US no matter whether you have got the plastic green card or not. The endorsement of your immigrant visa by the CBP officer at the port of entry is the proof of your permanent resident status which is valid for one year.
So, just show the endorsed immigant visa stamp on the passport to your HR to work and get paid. Print the webpage of this link and show it to HR if they do not accept the stamp:
