I spent a year traveling in SE Asia circa 2012 and I didn’t have any problems with my bank account. n=1 and all that, and I didn’t have income coming from outside of the US, but I had countless ATM withdrawals and credit card spends.
The only time a compliance officer has been in touch with me was when I was moving money to crypto exchanges.
The big factor is whether you change your address or not.
Keep your US address on there and VPN (though frankly I’ve never needed to for anything other than Charles Schwab) and you often glide through unnoticed.
2023 is very different to 2012. I remember back in the day you can open a paypal account with only an email and receive/send money with it. No kyc required.
Problem because it's not supported or problem due to fraud prevention by amex? I've travelled a lot and never had issues with amex or chase (once I used my chase credit card for the first time in over a year on the opposite side of the world and the transaction was instantly approved).
The compliance officer was following up with me I think because it looked like I was doing structured transactions, back when crypto exchange max ACH was $500/day. I did some explanation of crypto and he was like “so it’s for investment?” and that was it.
