Can my spouse get an "O" Visa in connection with my work permit? we are both americans. and if so, what is the process? do i have to take his documents with me to loas or ......? and can kids connect too?

also, this would be a new work permit not an existing one. thanks for your help.

No. But when/if you obtain a one year extension of stay from immigration she and children could obtain non immigrant O visa and then extend stay to match your extension of stay.
