Can Russian nationals extend their 90-day entry stamp in Thailand or switch to a different visa type?

For our Russian members please be aware that although you are currently allowed a 90 day entry stamp, this entry stamp cannot be extended. Nor can the entry be changed to any other visa type or extension. If you were planning to apply for an education visa, or a Non O for example you would need to ask the immigration officer to stamp you in for the “regular” 30 day visa waiver stamp rather than the current 90 day stamp.
