Green Card Travel Rules for Prospective Citizens. If you are an LPR who wants to become a naturalized citizen, any travel outside of the U.S. may be limited by continuous residency requirements. Generally, you must have been physically present in the U.S. for at least 30 months out of the previous five years to establish continuous residency. If you fail to meet this threshold, you may still be eligible for naturalization if you can prove that the absence was not an abandonment of resident status.
