A question for those who have experienced customs pre clearance. After preclearance are you quarantined until you board plane? I see a potential problem at PJA. Where is there space for quarantined passengers?
Yes, once you are admitted into the pre-clearance area you are, for legal purposes, admitted into the US. You may not leave the boarding area except for an emergency...and if you do leave you have to go through the whole screening process again.
BTW... The screening is done by U.S. agents on an overseas assignment.
My first experience with this process was several years ago when I was returning home from a business trip to Canada.
