I see you're posting from Dallas. There are multiple office bldgs with LabCorp offices and appts throughout town. Or use CVS: I haven't heard anybody being rejected that used a result from them.

Remember you have 5 days, counting departure day as day zero, not the 3 days the airlines are posting. Go to the USVI travel portal ASAP and familiarize yourself with the countdown for your test.

Anyway, the LabCorp website will let you select your appointment time. If you go to Medical City like I did, be advised that they don't do the swab, they do a blood draw testing for antibodies. You will have to have had the vaccine or recovered successfully from Covid to test positive for the antibodies.

I made the appt a full week before day 5, and I was first up @8:00, bldg "A". My test results were back in about 30 hours and I immediately uploaded them through the USVI portal. They gave me the "green square of acceptance" right at 24 hours.

I was tested on Friday, had the results on Saturday, was green lighted Sunday.

You will get emails from testing, reporting and then through the USVI portal.
