ธนาคารในประเทศแจ้งว่าการโอนเงินไปต่างประเทศเป็น 'กิจกรรมที่ผิดปกติ' หรือไม่?

It's pretty standard for banks to flag larger or unusual transfers, especially to international accounts, due to AML regulations. Many people break up larger sums into smaller, more frequent transfers to avoid immediate flags, though the bank will still be monitoring the overall activity.

This is fairly standard. Banks are obligated to flag anything that deviates from your usual transaction patterns, especially larger transfers to new destinations. It's less about the offshore account and more about their compliance requirements.
