INELIGIBILITY FOR a VISITOR VISA
The nonimmigrant visa application Form DS-156 lists classes of persons who are NOT eligible to receive visas under U.S. law. In some instances an applicant who is ineligible, but who is otherwise properly classifiable as a visitor, may apply for a waiver of ineligibility and be issued a visa if the waiver is approved.

HOW TO APPLY FOR A VISITOR VISA
You should apply for visitor visas at the American Embassy or Consulate with jurisdiction over your place of permanent residence (see links below). Although you may apply at any U.S. consular office abroad. However, it may be more difficult to qualify for the visa outside the country of your permanent residence.

DOCUMENTATION YOU WILL NEED
Every applicant for a visitor visa must pay a nonrefundable US$45 application fee and submit:

1) An application Form OF-156 (see links below), completed and signed. Blank forms are available without charge at all U.S. consular offices;

2) A passport valid for travel to the United States and with a validity date at least six months beyond the applicant's intended period of stay in the United States. If more than one person is included in the passport, each person desiring a visa must make an application;

3) Two photographs 1 and 1/2 inches square (37x37 mm) for each applicant, showing full face, without head covering, against a light background.

Optional Documentation
You should demonstrate that you are properly classifiable as visitors under U.S. law. Evidence must show;
· the purpose of the trip,
· intent to depart the United States, and
· arrangements made to cover the costs of the trip may be provided.

If you are traveling to the U.S. on business, you can present a letter from the U.S. business stating the business purpose of the trip, the intended length of stay and the companies intent to defray travel costs.

If you are traveling to the U.S. for pleasure, you can use letters from relatives or friends in the U.S. whom you plan to visit, or confirmation of participation in a planned tour.

If you are traveling to the U.S. for medical treatment you should have a statement from a doctor or institution stating the proposed medical treatment.

All applicants who do not have sufficient financial funds to support themselves while in the U.S. must present evidence that a someone in the US will provide support.
Visitors are not allowed to accept employment during their stay in the U.S.

ADDITIONAL INFORMATION
If your passport contains a previously issued visitor visa, you can inquire about special expedited procedures (available at most consular offices) for issuance of a new visitor visa.

Unless previously canceled, a visa is valid until its expiration date. Therefore, if you have a valid U.S. visitor visa in an expired passport, you can use it along with your new valid passport.
