I do believe as of May 1st there is no test required to enter Saba. Further there is no longer an EHAS entry form for Saba.
However on return to Sint Maarten, entry rules and the EHAS form is still mandatory..
I would suggest that you email a message to EHAS St Maarten and ask them directly . They are pretty good about responding to those type of questions.
