Buying Tether

Long story short, I am an American living overseas in Taiwan. I can't seem to buy any crypto without getting ripped off for terms of exchange rates. I have a coinbase account linked to my American bank account but all my money is earned and deposited into my Taiwanese bank. I have tried singing up to local exchange but they do not allow US citizens to use their platforms and my bank prohibits crypto purchases via Binance.

I am also unable to change banks or open a new one without a new work permit so, I feel stuck. I don't want to have to use ATMS and getting ripped off. I feel my only options are ATMs, and International wire transfers, neither of which are cheap.

Anyone have any idea how to get fiat into crpto in Taiwan without a massive headache?
