How long is an immigrant visa valid?
An immigrant visa is usually issued for six months. This will give the holder six months to finalize departure from the old country and prepare for arrival in the United States. It is a one entry visa and the holder will attain permanent resident status upon admission into the United States. Upon admission the visa will be endorsed by the immigration officer making it into temporary proof of permanent resident status, until such time as the actual card is produced and delivered to the U.S. address provided. Permanent resident cards cannot be sent to addresses outside the U.S.
