3 weeks before ETA, BUT, i am having a difficult time setting up a covid (rapid test) with proper detail info required on testing results, any info would be very much appreciated. I live in north central Massachusetts. Any input/info would be great.I can get the test at a local health care organization that would prepare the info i need on the health care's letterhead and a detailed description as required, will that be acceptable to get of the ground in the states as well as into this great island?
