I recd an email from a Wage and Hour Investigator to confirm my start dates with my employer. The email says that in an earlier interview questionaire I mention a date which is 2 months prior to the date that they have recd from other sources. (I do not even remember when I filled this questionaire) ;confused;. Also the dates mentioned are for the months of the year 2005. I have recently recd my green card and I have recd this email now. Should I be alarmed by this emai?. Am I obligated to respond to this email? The email does not say so. Please advice.
