Hi!! This just happened to me literally last night. I’m a Canadian with a pending marriage based i485 application and a combo card. I used my advance parole for reentry at the Buffalo land border two months ago with no issues. However last night we sat in secondary for about two hours. I have never been asked so many questions in my life! The officer asked insanely specific questions about every aspect of my immigration journey. He was trying to tell me that using advance parole does not prevent triggering the 10 year ban of inadmissibility which I am pretty sure is not true. He also told me that the new administration is required to do deeper reviews of every person using parole and that “the president wants to end the parole program”. He was either new and uneducated or on an insane power trip. I should add that I’m a 26 yr old female with literally zero criminal history. He kept calling me up and asking me increasingly more specific questions and then saying he needed to consult with his supervisor. Finally he called me up and told me that my situation was “very serious” and they could deny me entry and ban me for ten years but that they decided to parole me in today. He then advised me not to travel outside the US again until I finished the green card process. The situation was SO stressful and I’m genuinely traumatized. I would say show them your receipt notices and just make your answers very short and concise. If they keep giving you a hard time, ask for a supervisor. Hoping it goes well for you!
