US Citizenship & Immigration Services (USCIS) this week issued a notice warning immigrants to be aware of scams targeting foreign nationals over the phone and email:

Don’t be one of the victims! Scammers may call or email you, pretending to be a government official. They will say that there is a problem with an application or additional information is required to continue the immigration process. They will then ask for personal and sensitive details, and demand payment to fix any problems.

USCIS notes that their officials and representatives will never ask for payment over the phone or in an email. If they require payment for any reason, USCIS will mail a letter on official stationery specifically requesting payment.
