has suggested. It's a case of hoping for the best, but keep in mind even a negative test before you fly does not guarantee smooth entry, as you could easily test positive on arrival, so ensure you have insurance which covers this possibility (most insurances don't), as you will be required to go into quarantine which is an expensive venture for the uninsured. If you need assistance with the most appropriate insurance contact Arawan Namak who knows these situation inside out
