I totally understand what this visa is for. As mentioned in my post, I have been on the same Visa kind for years as I am the owner of a company and holder of a work permit in Thailand!! The reason for my question was, as I’ve been told that there is a new consul and that this may not be issued anymore. In fact, a lot of the embassies and consulates in Europe do not issue this Visa anymore.
, the border bounce before the visa expire date will definitely give you the extra 90 days, just make sure that your work permit is still valid long enough, so that you can still get the new Non B Multiple entry, when you go and apply for that later on....
