We will see, but most likely it will be a letter from a legitimate employer and bank statement showing a particular level of wealth or regular income, similar to the Business Visas you could get until recently. Previously, at many consulates you could get a 1 year Business visa without a Thai employer, usable by telecommuters or oil-fields style workers for instance, but that stopped maybe a year ago. Interesting that this got on the radar and might happen. Thai visas have not progressed for decades, and many changes have been regressive tightening of border regulation rather than tackling the sources of problems (mostly foreigners working without work permits, where making regulation more onerous punishes companies trying to follow the law and rewards the ones prepared to flout it).
