they typically only ask it of people they want to deny for spending too much time on tourist entries. If your sister has never been here before she is not the profile they are looking for and it's very unlikely they would ask. Having said that, it is the legal requirement.
it needs to be cash. It can be equivalent in a foreign currency, doesn't have to be THB. They typically only bring it up if they want to deny you for coming to Thailand too much on tourist entries. That isn't a legal reason for denial though, while not having the cash is, so it's used as the excuse. This is also why they won't let you withdraw it from an ATM, the whole point is to have a reason to deny you.
the EU collected €3bn in tariffs on €347bn of US imports in 2023, under 1%. It's now getting a 20% minimum tariff on everything from the US. The numbers Trump claims as reciprocal tariffs are a complete lie.
I filled out the MDAC while queuing for immigration and they didn't need it printed. Just needed it to have been done. There were posters in the immigration queue at KLIA explaining how to do it.
I don't think it's a policy change. Just that immigration and the embassies are independent and each can do it whichever way they want. For that matter there isn't consistency between each immigration office / embassy, they each interpret the rules their own way.
Wise has a substantially lower risk of default then many banks in developing countries, some of which have been basic bank regulation and low or no deposit guarantee schemes.
best rate is typically one of these fixed deposits. Bank of Thailand lists some here but there may also be special offers or other accounts not listed with higher rates, they don't seem to have this 2.4% which would be very good.
it's not that it's going to derail anything but if you can get 20k and the account is acceptable to immigration, why would you not take it? There's very specific rules as to when the money has to be there with the full balance needed for almost half the year.
Sounds easier and less stress to me to have a totally separate account for the 800k, earning interest, which you just leave alone.
Rather than moving money around and hoping you don't forget something or having an unexpected charge or direct debit bringing you down accidentally to 799,900 for 1 day (and yes they will reject for that).
