They will try to storm through this outbreak but I would be cautious to government dialogue and tone before proceeding. That said I am hoping to go soon. You can transfer through Singapore to Phuket last I checked
Looking at the current development in the world and how they previously acted I don't think you will be forced to leave. Just make sure you have an exit strategy for that just in case. Yepp don't expect but plan for it.
I think it depends on what country you are in. WU is really expensive and bad rates here but if I need to ensure direct transfer not that many choices... Remittance seems to be done by some here due to high amount of guest workers by small actors so I would not limit myself to the big ones if you really after best rate/fee.
Personally I use Wise but might have to compare again soon just feel it is so convenient. I also use their card for better rates abroad.
