If you don’t like to waste time at immigration, just go to an agent. For little money they will provide you with a 30 days extension. Before I had my NON-O visa I did it many times. My agent charged me 500 THB for this support. I handed over my passport, picture in the morning and afternoon same day I had my extension stamped. Don’t take the risk of overstay.
It‘s clearly mentioned that the Visa is valid for 90 days, that means if the visa was issued on 01. March you can enter Thailand till 29. May. After entering Thailand you can stay 60 days, with the option of one extension of 30 days. So finally you can stay with extension 90 days. However it’s just a 60 days TR Visa.
No problem, after every entry the 90 days rule starts from zero. No matter how much time you spend abroat. I’m using since 12 years Non-O with multiple entry and I’ve never been to the 90 days report because I always left Thailand before due to business reason.
😀 I don’t mind how they stay in business as long as I can send my money free of charge. They are using normal exchange rates (Same rates like big Banks in GER and THA). I use them now since more then one year and transferred many times amounts between 1000-3000 €. Always fast and without any complaints.
I’m using XE App on Mobile Phone. No costs at all for bigger amounts (>1000 €). Transfer from my German Account to XE Account in FRA, then to Bangkok Bank. Fastest transfer time up to now was 4 hours.
