Immigrant Visa Codes
These are the codes that USCIS and the US State Department use to designate the legal basis for immigrant visas. Each code identifies a separate legal basis for issuing an immigrant visa. An applicant may qualify on more than one legal basis, but will generally need to choose a single legal basis for an immigrant visa.
