there are private schools in Chiang Mai, Phuket, Pattaya, Prachuap, and Surat Thani that have ALL found ways to 'grease the wheel' and get in country 90 day non-ED visas issued from their immigration offices.
You can't do it in Bangkok, that's 100% certain but in the cities I mentioned there are schools that CAN do it
