Is it possible to add a multiple entry, or even single re-entry when I soon will be in Thailand on my second 90 non-B?

 

Will file for work permit & 1 year extension as soon as possible, also registering marriage, but might have to do a quick detour during the whole process...

You can get a re-entry permit that keep the remainder of the 90 day entry valid when you enter the country. 

The re-entry permit will expire on the day your 90 day permit to stay ends.

Thanks a lot! Tried to find a thread on this that was already here, but to no avail - so I posted this & kinda expected you'd reply!

You are really doing a LOT here, and for me personally stuff feels much safer & less confusing when you reply ????
