I’m doing the exact same next month from Las Vegas to Thailand — 3 large suitcases. Instead of shipping, am flying business class which allows 3 checked suitcases.
Otherwise Thai customs can be a hassle when shipping.
— The STV is very easy and given same day here. This is the one good thing.
— I gathered all my info for the retirement visa but overlooked the health insurance (I did purchase the health COVID insurance). Otherwise I have all required docs.
— arriving from Taiwan the retirement visa is only good for 90 days max (pending extension)
Without the health insurance doc, I walked out of the Taipei Thai embassy with a STV only.
