@Robert ******
non imm b is granted if you are married to a Thai or not. The non imm o based on marriage is linked to your relationship to a Thai. Thus your visa dont only depend on your business making a success but also your marriage. Purely from a business sense the non imm b is beter and more stable option for a businessman, which the OP seems to be. As for the changes to the non imm o based on marruage I did say I dont know if its still going to happen. I just repeated what the IO said. As can be expected he did not go into details. Lets wait for this week as the scheduled date was the 22nd April 2562 for these changes.
