是申請的reentry permit，因為有綠卡。如果收到recepit卻遲遲收不到打指紋通知可以離境嗎？

-Yes.

肯定中間也無法回美國打指紋了，如果離境以後收到打指紋通知卻不去打指紋，除了會導致申請被拒還有其他負麵影響嗎

-No. You need to return to US withon one year if the reemtry permit is denied. If you receive the biometric appointment and you cannot come back to do it, you need to return to US withon one year because the reemtry permit will be denied. 

If you do not receive the applointment, most likely USCIS may use your old biometrics in the system ans thus, they will approve your application (it is very common in these dats).
