Okay, as
@Robert ******
said, you CAN indeed both apply for 90 day single entry Non-Immigrant Type visas (the husband for a Non-B single entry and the spouse for a Non-O single entry) at the same time in Penang.
Have your husbands employer call Penang and ask the requirements as far as the letter from the company stating they have no problem with you getting a Non-O (trailing spouse) visa when your husband applies for a Non-B and what if anything needs to be done with the marriage certificate (if you're not married here in thailand).
