A lawful permanent resident (LPR) of the United States is required to present a valid Form I-551, Permanent Resident Card, if seeking readmission to the U.S. after a temporary absence of less than one year. A Transportation Boarding foil facilitates boarding by the airline to transport you back to the U.S.
Citizens of Visa Waiver Participating countries (like Sweden) going to the US for tourism or business* and who will stay for 90 days or less might be able to travel without a visa on the ‘Visa Waiver Program’ which is administrated by the Department of Homeland Security.
Starting July 1, 2019, individuals who wish to file the I-407 – Abandonment of Lawful Permanent Residency should send their I-407’s directly to the USCIS Eastern Forms Center in Williston, Vermont.
The Form I-407 will no longer be accepted by international field offices.
