I have have a G-1 visa that is technically valid forever (and exempt from the new regulations), but it's in a passport that expired ten years ago...</font>
As of February 1, 1995 all visas initially issued with "indefinite" validity have been deemed to expire 10 years from the date of issue. Hence, the visa is no longer valid.
However, any visa located in an expired passport remains valid provided it has not been defaced or damaged and it is within the visa validity period (maximum of 10 years).
