Hi everyone. The plan is to fly into Thailand in September. I have booked asq hotel which I can easily cancel and some flights with KLM on a flexible ticket. How far ahead do I need to do the COE application? It's asking for a vaccination certificate which I don't have yet due to only having one vaccination so far. Also do I need to get my visa and insurance before doing the COE? Or can I apply then add those things in after?
