This webinar will provide an overview of how the unlawful presence inadmissibility grounds, also known as the 3-year and the 10-year bars, work. Additionally, we will review the so-called permanent bar. We will discuss in detail when and to whom each of these bars applies, and identify when they can be waived. This session is an excellent complement to our "Waivers for Unlawful Presence: the I-601 and the I-601A Provisional Waiver" webinar.
