How to check to see if it is the IRS contacting you:
http://www.irs.gov/uac/Report-Phishing
"The IRS does not initiate contact with taxpayers by email to request personal or financial information. This includes any type of electronic communication, such as text messages and social media channels."
You receive a phone call or paper letter via mail from an individual claiming to be the IRS but you suspect they are not an IRS employee …
Phone call:
Ask for a call back number and employee badge number.
Contact the IRS to determine if the caller is an IRS employee with a legitimate need to contact you.
http://www.irs.gov/uac/Contact-Your-Local-IRS-Office-1
If you determine the person calling you is an IRS employee with a legitimate need to contact you, call them back.
Letter or notice via paper mail:
Contact the IRS to determine if the mail is a legitimate IRS letter.
If it is a legitimate IRS letter, reply if needed.
If caller or party that sent the paper letter is not legitimate, contact the Treasury Inspector General for Tax Administration at 1.800.366.4484.
"If you receive a phone call, fax or letter in the mail from an individual claiming to be from the IRS but you suspect they are not an IRS employee, contact the IRS at 1-800-829-1040 to determine if the IRS has a legitimate need to contact you. Report any bogus correspondence."
I had also got a call Yesterday. He spoke very confidently as a officer from IRS...Morgan. ..lol .Its a scam written all over it. He told all the crap about I owe money to IRS n all, will deport me. I just told him I will call him back, later he called me back again after an hour to collect the money and after searching everything online, I knew it was scam, the bad words which I gave him ...uffff. I then went back home and again called on that number from unknown number and just blasted them with bad words. If you call on that number they pick up and say IRS..lol
F.Y.I
(The intent of the fake call is to collect money in the sum of $2550 in a form of a voucher purchased at vouchergreen.dot or moneypak from a 711 or Walgreen stores. The call was made from a phone number 202-600-4440. They will threaten team members with deportation for errors on the I-94 (Alien Registration Number was not filed properly). Try to get as much upfront information from them as possible and under no circumstances give them any information. They will say they are from the UCICS. There is no reason that the IRS or UCICS or Department of Homeland Security should be contacting you.)
The thing is - scammers use call "spoofing" to make numbers look like they're from the IRS or other legitimate agencies. So just because a number shows up on your caller ID does not mean it's actually a legitimate agency or organization calling. That's why you should always be careful of people calling saying you owe this or that. ALWAYS research and find out for yourself if what they're saying is true BEFORE paying money. Plus, as stated, the IRS and USCIS would only contact you via mail if you did owe them anything. They NEVER call and threaten over the phone.
Why should you feel humiliated? YOU HAVE DONE NOTHING WRONG! You're also very new to the US and because you don't know how things work here, you've been scammed out of hard-earned money. If anything, you should get angry at the scammers and focus on letting others know what you've gone through so that they don't fall for the same scam.
