I have booked my flight to HCMC (Jan 4th to 9th) to apply for a Non O single entry (intend to extend based on marriage). I am an American currently on Non O-A (retirement extension.) I have read all the requirements as given on this website.
Question: Do I need to make an appointment at the Thai Consulate in HCMC? I cannot find a place on their website to make an appointment.
