How long does it take for a Thai tourist eVisa to be approved?

I had to leave Thailand at the end of my 60 days and go to Cambodia. I submitted the E visa to the Thai embassy in Phnom Penh (online). I had heard some people say it could come as soon as three days. On the phone, the Embassy told me it could be up to 10 business days (which means two weeks). I am hoping it does not take that long.

However, here in Cambodia prices are so cheap. It’s not a problem to stay. I have a really nice room with a balcony, at a hotel with a rooftop swimming pool. It is near pub Street where all the night life is, and is only $27 (U.S.) per day!!!!

Should be just a few days.

You didn't give where you are applying, so no one can answer your question. Some embassies take 2 days, and some take more than a month. The website of the embassy you're applying at normally has their processing time for evisa.
