持回美纸（Advance Parole）离境会触发非法居留禁令吗？
有可能。根据移民上诉委员会（BIA）于 2026 年 8 月 13 日对 Matter of Delcarmen-Lara 作出的裁决，持回美纸（Advance Parole）离境，在适用非法居留禁令（unlawful presence bars）时将被视为一次“离境（departure）”，推翻了此前适用十余年的相关规则。
因此，如果您此前累计非法居留超过 180 天但不足一年，离境可能触发 3 年入境禁令（3-year bar）；如果累计非法居留达到一年或以上，则可能触发 10 年入境禁令（10-year bar）。
该裁决仅适用于未来的离境行为（prospectively），不会追溯适用于该裁决作出前已经发生的离境行为。凡有非法居留历史的人士，在使用回美纸出境前，都应先评估相关移民风险。

No. The BIA expressly made its August 13, 2026 decision prospective, so advance parole trips taken before that date are generally not affected by the new rule. Future travel should still be reassessed, particularly for DACA and TPS holders who may have accrued significant unlawful presence before receiving DACA or TPS.
Not necessarily. An approved I-601A provisionally waives certain unlawful-presence inadmissibility, but it is designed for applicants who will depart the United States to complete immigrant visa processing at a U.S. consulate. It does not make travel on advance parole generally risk-free or waive other possible grounds of inadmissibility. If you have accrued unlawful presence and are considering travel on advance parole, the effect of any approved or pending I-601A should be evaluated before you leave the United States.
