It's a scam. The person will call and pretend to be a homeland security officer and ask you to transfer some money via western Union to some foreign country. Don't listen. Cut it off. They are running this racket for long time.

Yes, even i also got a call from this number today. he was saying that my wife's visa in problem and she needs to leave the country or so.. and some files have sent from my home country and that and thissss........ etc etc.....
don't listen to such people..... just cut down or try to call cops.

Called and told like, we are calling from Homeland security, immigration departmetn. There is a legal case on you and threatened me. As part of verification, he made me to tell about my & my spouse identity. (Suspected ID theft).  Do not listen, cut the call.

same happened with me today,,I got a call from this no 4848339002 .He told me that my wife has not updated her  USCIS A no  and her immigration status is on challenge and they will go ahead and terminate her immigration status. Before I could ask something about how do I update it now he disconnected the call.
