8 U.S. Code § 1201 - Issuance of visas
Each alien who applies for a visa shall be registered in connection with his application, and shall furnish copies of his photograph signed by him for such use as may be by regulations required. The requirements of this subsection may be waived in the discretion of the Secretary of State in the case of any alien who is within that class of nonimmigrants enumerated in sections 1101(a)(15)(A), and 1101(a)(15)(G) of this title, or in the case of any alien who is granted a diplomatic visa on a diplomatic passport or on the equivalent thereof.
An immigrant visa shall be valid for such period, not exceeding six months, as shall be by regulations prescribed, except that any visa issued to a child lawfully adopted by a United States citizen and spouse while such citizen is serving abroad in the United States Armed Forces, or is employed abroad by the United States Government, or is temporarily abroad on business, shall be valid until such time, for a period not to exceed three years, as the adoptive citizen parent returns to the United States in due course of his service, employment, or business. A nonimmigrant visa shall be valid for such periods as shall be by regulations prescribed. In prescribing the period of validity of a nonimmigrant visa in the case of nationals of any foreign country who are eligible for such visas, the Secretary of State shall, insofar as practicable, accord to such nationals the same treatment upon a reciprocal basis as such foreign country accords to nationals of the United States who are within a similar class; except that in the case of aliens who are nationals of a foreign country and who either are granted refugee status and firmly resettled in another foreign country or are granted permanent residence and residing in another foreign country, the Secretary of State may prescribe the period of validity of such a visa based upon the treatment granted by that other foreign country to alien refugees and permanent residents, respectively, in the United States. An immigrant visa may be replaced under the original number during the fiscal year in which the original visa was issued for an immigrant who establishes to the satisfaction of the consular officer that he was unable to use the original immigrant visa during the period of its validity because of reasons beyond his control and for which he was not responsible:
Prior to the issuance of an immigrant visa to any alien, the consular officer shall require such alien to submit to a physical and mental examination in accordance with such regulations as may be prescribed. Prior to the issuance of a nonimmigrant visa to any alien, the consular officer may require such alien to submit to a physical or mental examination, or both, if in his opinion such examination is necessary to ascertain whether such alien is eligible to receive a visa.
Each immigrant shall surrender his immigrant visa to the immigration officer at the port of entry, who shall endorse on the visa the date and the port of arrival, the identity of the vessel or other means of transportation by which the immigrant arrived, and such other endorsements as may be by regulations required.
Each nonimmigrant shall present or surrender to the immigration officer at the port of entry such documents as may be by regulation required. In the case of an alien crewman not in possession of any individual documents other than a passport and until such time as it becomes practicable to issue individual documents, such alien crewman may be admitted, subject to the provisions of this part, if his name appears in the crew list of the vessel or aircraft on which he arrives and the crew list is visaed by a consular officer, but the consular officer shall have the right to deny admission to any alien crewman from the crew list visa.
No visa or other documentation shall be issued to an alien if (1) it appears to the consular officer, from statements in the application, or in the papers submitted therewith, that such alien is ineligible to receive a visa or such other documentation under section 1182 of this title, or any other provision of law, (2) the application fails to comply with the provisions of this chapter, or the regulations issued thereunder, or (3) the consular officer knows or has reason to believe that such alien is ineligible to receive a visa or such other documentation under section 1182 of this title, or any other provision of law:
Nothing in this chapter shall be construed to entitle any alien, to whom a visa or other documentation has been issued, to be admitted  the United States, if, upon arrival at a port of entry in the United States, he is found to be inadmissible under this chapter, or any other provision of law. The substance of this subsection shall appear upon every visa application.
After the issuance of a visa or other documentation to any alien, the consular officer or the Secretary of State may at any time, in his discretion, revoke such visa or other documentation. Notice of such revocation shall be communicated to the Attorney General, and such revocation shall invalidate the visa or other documentation from the date of issuance:
 So in original. Probably should be followed by “to”.
