After an arrest, usually in several days, a USICE officer issues a document called a “Notice to Appear” which sets forth the reason(s) why you ought not to be permitted to remain in the United States. If you are here illegally or if you have committed a serious criminal offense – which as explained here, can be misdemeanors – you will be issued a “Notice to Appear” and will be required to address any defenses and/or waivers with an immigration judge.
