THIS IS USCIS ...
THEY ARE GOUVERMENT DEPARTMENT WHO IS HANDLING IMMIGRATION CASE FILES ...
I THANK THEM VERY MUCH THEY HELP ME AND MY FAMILY TO GET LEGALISED HERE IN USA...
My wife received call from this number and she gave to me. He (looks like Indian) said he was calling from Homeland Security, DC and that somebody from back home has filed law suit against her. Need to be very careful.
they made multiple back-to-back calls for 3 hours straight and we ignored them.
If anyone picks up and the caller makes threats, call the police and post on the web and publicize the number and the incident.
That is the best way to protect yourself
