Overview - About Returning Resident Visas 概述-关于返回居民签证
A permanent resident (called lawful permanent resident or LPR) or conditional resident (CR) who has remained outside the United States for longer than one year, or beyond the validity period of a Re-entry Permit, will require a new immigrant visa to enter the United States and resume permanent residence. A provision exists under U.S. visa law for the issuance of a returning resident special immigrant visa to an LPR who remained outside the United States due to circumstances beyond his/her control. This webpage is about Returning Resident Visas. If you are an LPR unable to return to the United States within the travel validity period of the green card (1 year) or the validity of the Re-entry Permit (2 years), you may be eligible and can apply at the nearest U.S. Embassy or Consulate for a Returning Resident (SB-1) immigrant visa.
