Is my Thai spouse required to accompany me for a yearly extension of my non-immigrant O visa?

Hello all,

I would like to ask about the yearly extension of a non-immigrant O visa (Thai spouse). When we apply for the yearly extension at the immigration office, it is necessary that the Thai spouse (Thai wife in my case) accompany the applicant to the immigration office as well? Or can the applicant apply at the immigration office on his/her own (if we have all the documents required)?

I look forward to hearing any advice on this matter.
