According to the INA, it is a federal crime for any non-criminal alien to illegally enter the United States after that alien has been denied entry, excluded, removed, deported, or if he or she has departed the United States while an order of removal was outstanding. The maximum sentence for this crime is 2 years of imprisonment. However, if he or she was a criminal alien and "whose removal was subsequent to a conviction for commission of three or more misdemeanors involving drugs, crimes against the person, or both, or a felony (other than an aggravated felony), such alien shall be fined under title 18, imprisoned not more than 10 years, or both."
