USA Visitor Visa:

Introduction:
Visitor/Tourist Visa is a non-immigrant visa issued to people entering U.S. temporarily for business (B1), or for pleasure, tourist, medical treatment (B2). These are generally issued up to a period of three months to ten years. An additional extension of six months can be obtained based on the approval by the INS, while the visitor is in USA.

Requirements:
Under U.S. law, candidates for visitor visas must qualify on their own for visas to visit the United States.
This is what candidates must do when they apply for visitor visas:

• Complete and sign the required application forms;
• Bring evidence that their visit is temporary and that they will leave the United States after their legally authorized stay; and
  
• Undergo security clearance procedures
  

All visa applicants, even babies in their parents' passports, must have these things:

• Application Form DS-156 , completed and signed
• Current, valid passport or travel document
  
• Photograph. Requirements are strict for photograph size, type and quality. Please check with your nearest consulate for specifications before you get your picture taken.
  
• Application fees. All applicants must pay the application fee. Some applicants, according to nationality and type of visa, must also pay an issuance fee.
  
• Evidence of funds to cover your expenses in the United States
  
• Evidence of compelling social and economic ties abroad
  

For men between 16 and 45 years of age:

What happened after 9/11 -?

• Recent changes in United States visa policy and procedures may increase the amount of time it takes for foreigners who want to visit, to obtain a visa. It is important to apply early!
• Changes introduced shortly after September 11, 2001 involve extensive and ongoing review of visa issuing practices as they relate to our national security. For many applicants, a personal appearance interview is required as a standard part of visa processing. Visa applications are now subject to a greater degree of scrutiny than in the past. This can cause longer processing times. The State Department is working hard with other government agencies to streamline clearance procedures in ways that continue to protect United States borders, our first priority, while facilitating legitimate travel.
