Gather supporting documents that state the reason for your trip and your intention to remain for a specific, limited period. These may include your itinerary, return flight ticket and your accommodation arrangements. Prepare evidence of funds to cover expenses during your visit and documents that show social and economic ties abroad, such as a residence outside the United States and employment information that will ensure your departure at the end of your visit.
Apply to the U.S. embassy or consulate in your country of permanent residence. It is not impossible to qualify for the visa outside your country of permanent residence, but it can be more difficult for you to demonstrate ties to a country other than your place of permanent residence. With few exceptions for age and other criteria, an interview is required. Visa wait times for interview appointments vary.
Go to the U.S. embassy for your prearranged appointment time and date. Submit fingerprint scans and answer questions during the interview. You are asked about your travel plans. The burden of proving intention to return home rests on the foreign traveler. Documents showing family ties or employment may suffice for these purposes. Wait for application approval or denial notification. Visa processing times vary.
