No police or embassy asks for money by phone

This one drains accounts, not wallets — coverage of Vietnam's urgent mid-2025 nationwide scam warning documents individual losses from hundreds to hundreds of thousands of dollars. A caller claiming to be police, a prosecutor, immigration, or your embassy knows your name, then says your visa or bank account is tied to money laundering or a criminal case. The pressure follows: "verify" your funds by transferring to a safe account, install an "official" app, and keep the case secret. Scam centers now use AI voices, and tourists on local SIMs and foreign residents get polished English-language versions.
