, thanx to
@Ar***
you have the requirements needed to do an in country conversion from a 30 day visa exempt entry or a 60 day tourist visa entry to a 90 day Non-B without making the trip to the immigration office.
I'd say give those sheets to whoever pushes paper for you where you're employed and see if they can meet the requirements so you can do the Non-B in country. If not, I see another trip to a thai consulate in your near future ;)
Good Luck
