@george.butler237: Even with the 48-month automatic extension, things happen. Maybe your notice is about to expire, maybe you lost the physical receipt, or maybe you have an emergency trip and the letter hasn't arrived yet. Enter: The ADIT Stamp (I-551). 🛂 This stamp proves your lawful permanent resident status so you can board your flight and return to the US without the stress. Pro Tip: Don't wait until the week of your flight to request this! Call the USCIS Contact Center to get the process started—they can often mail it directly to you without an in-person appointment. Save this post so you don't forget, and share it with someone navigating the USCIS backlog right now! 📲 #ImmigrationLawyer #USCISBacklog #GreenCardRenewal #TravelHacks
