Remember, U.S. government and law enforcement agencies, including the IRS, U.S. Citizenship and Immigration Services (USCIS), ICE, the U.S. Department of State, and the police will:
Never ask for credit card, debit card or prepaid card information (such as Apple/Walmart gift cards) over the telephone.
Never request immediate payment over the telephone and will not take enforcement action immediately following a phone conversation. You would receive a notification from a US government office before any phone call is made to you.
