The U.S. Citizenship and Immigration Services (USCIS) issued a WARNING against SCAMMERS, which we copy here word for word:
“If someone claiming to be a government official or law enforcement officer calls making threats such as deportation, beware! Hang up and report it!
Here’s How it Works A number appears on your caller ID that may look like a legitimate government number. When you answer, the person on the phone poses as a USCIS or other government official or law enforcement officer.The scammer will say that there is a problem with your application or additional information is required to continue the immigration process. Then, they will ask for personal and sensitive details and may demand payment to fix problems. The scammer may tell you to make a money transfer or go to a store to purchase a money order, voucher or make some other type of money exchange, payment or withdrawal. They may threaten you with deportation or other negative consequences if you do not pay.
If you receive a call like that, we urge you to hang up immediately.
We will never ask for any form of payment over the phone or in an email. If we need payment, we will mail a letter on official stationery requesting payment. Do not give payment over the phone to anyone who claims to be a USCIS official. In general, we encourage you to protect your personal information and not to provide details about your immigration application in any public area.”
So, you need to be on guard against IDENTITY THEFT – of your own identity and also the identity of GOVERNMENT OFFICERS.
