From USCIS (edited)
Unlawful presence is any period of time when you are present in the United States without being admitted or paroled, or when you are present in the United States after your “period of stay authorized by the Secretary” expires. Unless an exception applies, you will be found inadmissible based on your accrual of unlawful presence if you:
➤Seek admission again within 3 years of leaving the United States before removal proceedings begin, after you accrued more than 180 days but less than 1 year of unlawful presence during a single stay;
➤Seek admission again within 10 years of leaving or being removed from the United States, after you accrued 1 year or more of unlawful presence during a single stay; or
➤Reenter or try to reenter the United States without being admitted or paroled after you accrued more than 1 year of unlawful presence, in total, during 1 or more stays in the United States.
Determining whether you are inadmissible after accruing unlawful presence can be complex. If you need help or legal advice on immigration matters, make sure the person helping you is authorized to give legal advice.
