因回美證要打指紋，時間不確定。而我也確實國內有事。請問一下，
1）官員的這次警告是真的，下次肯定不讓入關？還是有嚇唬的意思，入關還是要看不同官員？當然，如果還能入，我可能會在半年內回來。
-It is very risky if you don't have the reentry permit to reenter US after you leave US and most likely they will cancel your green card in this case.

Request an Expedited Biometrics Appointment
USCIS may expedite a biometrics appointment as a matter of discretion. In this case, it can take 7 to 14 days from filing to the appointment.[4]
To request expedited processing, you should include with your application a written explanation of the reason your travel abroad is urgent.[5] This should be supported by any available evidence of the urgency.
