If you are a Nepalese citizen and you want to apply for a visitor visa to travel to the United States, you will need to follow these steps:

Determine which type of visitor visa you need: There are two types of visitor visas available: B-1 (for business) and B-2 (for tourism and other non-business purposes). Most people who apply for a visitor visa apply for the B-2 visa.

Fill out the online nonimmigrant visa application (Form DS-160): You can find the application on the website of the U.S. Department of State. Make sure you complete the application accurately and honestly.

Pay the visa application fee: The fee for a visitor visa is $160. You can pay the fee online or at a designated bank.

Schedule an interview: You will need to schedule an interview at the U.S. Embassy or Consulate in Nepal. Wait times for interview appointments can vary, so you should plan ahead and schedule your appointment well in advance.

Prepare for the interview: You will need to bring several documents to your interview, including your passport, the confirmation page from your DS-160 application, a photo that meets the U.S. visa requirements, and any other documents that you think will help demonstrate your ties to Nepal and your intention to return home after your visit.

Attend the interview: At the interview, a consular officer will ask you questions about your travel plans, your ties to Nepal, and your intention to return home after your visit. Answer the questions honestly and confidently.

Wait for a decision: After the interview, you will be informed whether your visa application has been approved or denied. If your visa is approved, it will be stamped in your passport and you will be able to travel to the United States.
