you will have lost 11 months and your Non-Imm-O/A visa will become void unless you buy the insurance. And after 30 days you will technically be in overstay

the above apparently only regards the renewal of an EOS done out of a Non-Imm-O, not the Non-Imm-O/A

Paul Potter and the requirement 800,000 for the last TWO months before and 3 months AFTER application is not added yet, it says 3 months which used to be required for repeated EOS based on retirement applications, not for the first time. This is an OLD piece of paper, that's why the health insurance requirement is not mentioned. And nothing was mentioned as for the topic of your talk with them was conversion of your O/A to a Non-Imm-O visa based on marriage, no health insurance is needed for this. Actually, the Immigration officer offered & suggested to you a nice way out of the insurance requirement which he seems to be willing to do . . it is a "conversion" and not done by every Immigration in Thailand. You can call yourself lucky, You can 60 days later do the Extension of Stay based on thai spouse once you fullfill the requirements mentioned in the handout list, the 400,000 THB need to have been 2 months in your account

Katherine Staniforth you don't get a 1 year Non-Imm-O multi entry in London anymore, only a 90-days Non-Imm-O single entry. However you can get a 6 month multi entry tourist visa

. . and the quandry is the reason why I hate to spoil somebody's happy day and his expectations . . . . . . .

we know that beginning with November 7th after a meeting of immigration officials at the airport, it was agreed that FIRST entries at Suvarnabhumi Airport with an O/A issued before 31st of October 2019, were admitted without the proof of the health insurance. Numerous reports told the same. However it does not apply 100% when someone leaves and re-enters, or applies for the Extension of Stay

Martin Howarth I hate to spoil somebody's happy day. You wrote at the end: "So relived as I’ve got to leave the country numerous times this coming year" . . . this is where the problems could begin. . . . . If you take some time and check by the search function of this group, you might find quite a few reports which indicate that once after a trip abroad, on re-entry you will be asked for the proof of a thai based health insurance. Even when you got an O/A visa issued before the insurance rule came into effect. We still do not clearly & 100%-ly know what there is on the wait for you upon a re-entry. You might be given the additional 365 days admitted stay, or might be given a 30-day visa exempt and get told to buy a thai accredited insurance

i found this picture recently . . it explains the grandfathering rule . . . it shows the date as being 21st October 1998

right after, you can start the process of obtaining an Visa Non-Imm-O, by "conversion" from a 30 day exempt or a tourist visa. While fulfilling all the requirements.

Henry Zacks your current admitted stay will expire in July 2020 while you are on your second year of stay of a Non-Imm-O/A visa. We at this date do not know what will happen when you leave and re-enter Thailand. If you leave WITHOUT a re-entry permit, you have the chance that your O/A will become void, and you can enter Thailand with either a 30-day exempt visa or a Tourist visa obtained at an embassy or consulate in a neighbouring country
