This bill proposes substantial amendments to the Immigration and Nationality Act, primarily aiming to increase criminal penalties for individuals who illegally reenter the United States after being removed. It redefines "removal" to include stipulations made during criminal trials and revises the general penalty for illegal reentry to include fines and up to five years imprisonment. The legislation introduces new, more severe penalties for specific categories of removed aliens, such as those with prior convictions for certain misdemeanors or felonies, or individuals previously removed due to national security concerns. For example, an alien removed for terrorism-related inadmissibility would face a mandatory 10-year prison sentence that cannot run concurrently with other sentences, and those removed three or more times could also face up to 10 years. Additionally, the bill establishes mandatory minimum criminal penalties for the most serious offenses. Aliens previously convicted of an aggravated felony or those with at least two prior illegal reentry convictions would face a minimum of five years and up to 20 years imprisonment. These changes aim to create a stronger deterrent against repeated illegal entry into the country.
