here is what I found from the Q&A section of
https://www.ict.go.cr/en/documents/mate ... /file.htmlQuestion #12 Can I travel to the USA if I already had COVID-19 and recovered?
If you tested positive on a PCR or antigen test within the last three
months, and have complied with the isolation criteria, you may travel if
you show the positive result of the test and a letter from your healthcare
provider or a public health official, stating that you are authorized to
travel because you have recovered. The positive result of the test and
the letter are referred to as the "recovery documents.” If the recovery
period is longer than three months, the test must be taken again.
hope that helps. this is the original website:
