Hi
We are two ( 1Swedish and 1French passeport ) we crossed border three times :
-By sail yatch check in koh lipe 5 December 2019 to 14 December 2019
-by s.y 22 dec 2019 check in Phuket, extended visa for 30 more days .
-went to Myanmar with s.y on 6 February comeback to Thailand 25 February and get new visa on arrival .
And here comes the question . We would like to do our dive master in Koh Tao , so we ll need at least 60 days plus 30 .
How this can be done .... thank a lot
