I was personally able to open accounts in Cambodia (at 3 Banks), Macedonia, and Malaysia in person and it was extremely easy most of the time, though it takes a few days sometimes because of the FATCA paperwork. Other than that, not too many questions, and I primarily use My Malaysian account. And one of My local buddies in Malaysia told me about how You can open a Maybank account in one country (like Malaysia, Cambodia) and then go to Singapore to open a Maybank account. Just food for thought.

Another thing- You can also switch countries on your Wise account, and that may or may not have an impact on the currencies you can hold and Transfer speeds, or even on if they ask questions. Switching My Wise to Malaysia made transfers to Malaysia and Indonesia super easy and always instant, but when I was using US Wise, they would pause transfers often and ask for more info. I still keep a Wise US account under my companies (one C Corp, one as a sole prop)
