TLDR : Answer Summary
The upcoming Smart Visa in Thailand aims to attract highly skilled workers, investors, and executives in specialized industries. It is expected that only foreigners earning over 200,000 baht/month in fields like technology and healthcare will qualify. There are concerns that the visa's stringent requirements may exclude many traditional expats and digital nomads.
