I've heard saliva tests only take 15 minutes for results. Someone could make a bundle if they set these up in airports across the world. I wonder if you can pre purchase these and take them with you and have a dr/nurse/medical authority administer it and sign off. I hope to return to sxm someday but not this year. last there for a week stay in 2017, 2018 got canceled due to hurricane. was there for a day last march on a cruise.
