Here's the email we received from the USCIS today:

Immigrants all over the country are being targeted for phone scams. Don't be one of the victims!

Scammers pretend to be a government official and call immigrants saying there is a problem with their immigration record. Sometimes they know personal information about the immigrant. They ask for personal and sensitive details, and demand immediate payment to fix the problem. They get angry and threaten people with deportation if payment is not made immediately with electronic money transfers.

Sometimes, scammers use special software to make it look like our 800 number is calling. Other times they leave a message to call a number that sounds exactly like our 800 number.

Remember, USCIS officials rarely call customers on the phone, and WE WILL NEVER ASK FOR PAYMENT OVER THE PHONE. If we need payment, we will send a letter on official stationery requesting payment.

If you receive a call like this, hang up and report it to the Federal Trade Commission at www.ftccomplaintassistant.gov.
