This is incorrect. In the federal system, while felonies are punishable by imprisonment over a year and misdemeanors by imprisonment up to a year, the important word is punishable - whether the crime is a felony or a misdemeanor is simply inherent to the charge, and if you are convicted, the nature of the crime doesn't change based on the imposed sentence. E.g. if you are convicted of a felony but receive a prison sentence of a year or less, you're still a felon - the charge doesn't just turn into a misdemeanor because you received a shorter sentence.
