The process of applying for a United States visa from Bangladesh involves several steps. The specific visa category you need depends on the purpose of your visit, such as tourism, business, study, or work. Here is a general outline of the process for obtaining a non-immigrant visa, which covers temporary visits to the United States:

1. Determine the visa type: Visit the U.S. Department of State’s website (https://travel.state.gov) to determine the appropriate visa category for your purpose of travel.
2. Complete the DS-160 form: Fill out the online Nonimmigrant Visa Application (DS-160) form, available at https://ceac.state.gov/genniv/. Make sure to answer all questions accurately and completely. After submitting the form, you will receive a confirmation page with a barcode, which you must print and bring to your visa interview.
3. Pay the visa application fee: The non-refundable visa application fee varies depending on the visa type. Follow the instructions provided on the U.S. Embassy in Bangladesh website (https://bd.usembassy.gov) to pay the fee. Keep the receipt as proof of payment.
4. Schedule an appointment: To schedule your visa interview, visit the U.S. Embassy in Bangladesh’s website and create an account. Log in to your account and follow the instructions to book an appointment at the U.S. Embassy in Dhaka. You will need your DS-160 confirmation number, visa application fee receipt, and passport information to schedule the appointment.
5. Prepare the required documents: Gather the necessary documents for your visa interview. These may include:
   • A valid passport
   • DS-160 confirmation page
   • Visa application fee receipt
   • Appointment confirmation letter
   • A passport-size photograph that meets U.S. visa requirements
   • Documents supporting your visa application, such as proof of financial resources, employment, and travel itinerary (specific requirements vary depending on the visa type)
6. Attend the visa interview: Go to the U.S. Embassy in Dhaka on the date and time of your appointment. Bring all the required documents, including your appointment confirmation letter. During the interview, a consular officer will ask you questions about your purpose of travel, your background, and your plans in the United States. Answer all questions truthfully and confidently.
7. Wait for the decision: After the interview, the consular officer will inform you whether your visa application has been approved or denied. If approved, your passport will be sent to you with the visa attached. If denied, the officer will explain the reason for the denial and whether you can reapply in the future.
