will use passpost for travel to Korea by Feb but passport under admin processing as of Dec 15, 2016

I have a planned travel to South Korea by Feb 20, 2016 but paspoort is under admin processing as of Dec. 15,2016. If it’s not returned before Feb, can I retrieve my passport and return it back after my travel?

Is your passport under administrative processing at the US Embassy, Korean Embassy or your home country passport office? Also, if you have a Korean visa on your passport, the US embassy will hold your passport for additional review. Give it time till January 15th.

Best wishes
