Vientiane is the normal place for those in Chiang Mai. Present yourself at the Embassy in the morning to make application and pay the fee/submit the form/provide the photo(suspect photo copy of front passport/data page also required). Pick up next workday afternoon. You can travel visa Udorn Thani to Nong Khai to Vientiane and back.
