The U.S. Immigration and Nationality Act requires that your eligibility for a non-immigrant visa be determined on the basis of strong, well-established ties to a residence outside the United States, as well as on the basis of reasonable, credible plans for your visit to the United States. During the interview the officer might ask to see one or more of the following documents (translated into English):
a) an original, current letter of employment with job title, length of service, and monthly salary
b) personal bank statements for the last six months
c) photocopies of current trade license and current audited financial statements for the past two years showing status of business
d) property deeds
e) current letters of invitation from American companies or conference organizers
Non-immigrant visas are usually granted for a maximum of six months. However, your length of stay depends upon the discretion of your immigration officer.
Also, keep in mind that you are not allowed to work with a B1 (business visa) or B2 (pleasure visa). If you wish to work in the United States, you must apply for either the H-1B or H-2B visa.
