And I think at this point we pretty much beat to death the "unicorn" year-long, multi-entry tourist visa that
@Ka***
holds.
It IS a real visa, issued from a REAL thai consulate and as such should be accepted and you should get stamped in for the number of days you're entitled to when you enter the country on it (60 days) as long as it's valid.
AND just like all multi-entry visas, exiting/re-entering just prior to the VISA itself expiring (in your case on or before 16th of April 2020) will get you a final 60 day entry which you can extend for 30 days at the immigration office for 1900baht.
We wish good luck to the O/P and their 'unicorn visa" :P
Have a safe and happy new year (y)
