Got to do my non immigrant o visa extension based on thai wife next week. I know that you can't make an online appointment, do you still have to get to Chaeng Watthana at 6-30/7-00 am to get in the queue?
TLDR : Answer Summary
The user is inquiring about the need to arrive early at the Chaeng Watthana Immigration Office for an appointment to extend their Non-Immigrant O Visa, which is based on being married to a Thai citizen. Comments reveal that online appointments are now available for visa extensions based on marriage and raising half-Thai children, suggesting that the need to queue early may no longer be necessary.
