Can I get a three-month category 'O' visa in Laos? What about a double-entry non-immigrant B in Penang?
To be honest I hate answering these kind of questions because there is no such thing as a straight yes or no in my experience.
My advice is always to either call or fax the Thai consulate you intend to go to (calling is better) and get the answer from the actual consulate officers. Ask the name of the person you are speaking to so you have a reference point.
I wouldn't plan a visa run - transportation, accommodation costs, etc - unless I had some sort of guarantee.
If you turn up at the consulate with ten bits of paper, and the consulate want eleven, then it's too late. You're screwed.
Find out exactly what you need before you make the journey.
