Ours were really quick. Like maybe an hour to get the PAY US $40 email, then once you pay the QR Code/VISA can be clicked on immediately and screenshot.
They are not clear enough that people should check the application website proactively - that triggers a prompt to pay and then you are done.
But keep checking.
A PCR needs to be take within 3 days of the travel date, is the travel date itself counted? Meaning, is today, Thursday, within 3 days of Sunday or not?
yes, if your arrival is Sunday then you need to take the test thursday.
The official website states test taken no more than three days (72 hours) prior to the date of arrival. What do they mean by 72 hours? Do they mean 72 hours prior from the arrival time or we can test anytime 3 days prior.
