因回美证要打指纹，时间不确定。而我也确实国内有事。请问一下，
1）官员的这次警告是真的，下次肯定不让入关？还是有吓唬的意思，入关还是要看不同官员？当然，如果还能入，我可能会在半年内回来。
-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.
