Thank you for your precious help, sorry but I was busy till now and I could not replay.
I checked well my Passport pages and I realized that I already had a Re-entry permit stamped on my passport, this is the reason I edited my post, because my question was redundant. I kept instead the second question.
By the way , this is my first time I obtain a long term Visa so I do not have the knowledge that you guys have. That is why I am asking.
What type of Visa do I have, I checked well:
1) there is a stamp on March 3rd 2023 that says NON "O" Retirement with expiration is May 31st 2023, then under it is written , before leaving Thailand please apply for a re-entry Visa (I think this is because at the moment it was still a "single entry " Visa.
2) the page after that has a stamp that says that my non "O" was USED and the stamp USED on It.
3) The page after that is a page where there is a stamp with written "Extension of stay permitted till May 1 2024 and it is dated 13 March 2023 Under this stamp there is tagain the invitation to do a Re-Entry permit before leaving Thailand , this because till now it is still a single entry situation)
4 the last stamp is in the followinf page and it says "NON IMM" RE-Entruy Permit , persons:ONE, Number of Entries: MULTIPLE, Lenght of Stay : 31 st May 2024
I assume it is an extension of a non "O" is that correct?
So I assume also that I already have the re-entry permit and it is not necessary to provide the insirance at the moment of entry but I will do once in Thailand again.
Is that everything correct and understandable?
Thank you for all your interest and patience
