Flying into USA via Europe/Singapore on Advance Parole (AP)?

[pagetrip]

I am seeking clarification on the use of Advance Parole (AP) for re-entry into the United States after international travel. Specifically, I am planning to return to the US from India with a layover in either Europe or Singapore. This will be my first time using Advance Parole. I possess an H1B visa stamp in my passport valid until 2026, but I am no longer employed by the sponsoring employer. Although I recently traveled from the US to India with a layover in London, I understand that regulations regarding AP travel may differ for departures and returns. Additionally, I am exploring cost-effective travel options and have observed that Middle Eastern airlines are generally more expensive than European carriers. Thank you for your time and expertise.

Thanks.

I flew back to the US on AP through Frankfurt without any issues. Just made sure to carry my combo card, passport, and copies of my I-485 receipt and AP documents.

Thanks for sharing your experience! I'm in a similar boat and planning my return on AP soon. Did the airline staff in Frankfurt ask any specific questions or documents before boarding the US-bound flight?
