Around 7 business days, almost 3 weeks, because it happened during different holidays in Thailand and Poland. It’s worth noting that embassies observe holidays in both countries.
I see. I just logged in to online reporting and it says there:
According to The Immigration Act,B.E.2522,the foreigner who has received a temporary stay permit and stayed in the Kingdom of Thailand over 90 days must notify his residence to immigration officer every 90 days.
I haven't received any stay permits, so not sure why should I report?
Is this your assumption or you know the legal basis of it? I am curious. For example, in Indonesia, you can promote your company but you are not allowed to conduct a business transaction - that would have to go through an overseas entity.
