I answered and it was a lady in an Indian accent.  She sounded like she was calling through Skype.  She asked for Mrs. Sawant.  I said that's me.  She said she was calling from US Immigration department and then she asked me to verify my first name.  I told her that she should have that information in front of her, I told her I will verify my first name if she would give me the correct answer of my first name over the phone.  Silence ensued.  after a minute of waiting, I said goodbye and hung up.
