Landing Pass Extension Act of 2020 This bill allows a qualified alien crew member of a vessel to obtain a permit to land temporarily in the United States for up to 180 days, where currently such permits generally do not allow for stays exceeding 29 days. Specifically, an immigration officer may grant a crew member a 180-day landing permit if the officer is satisfied that the crew member (1) intends to depart within the prescribed period on a vessel other than the vessel the crew member arrived on, and (2) will perform ship-to-ship cargo transfer operations to or from a vessel engaged in foreign trade.
