To obtain a US tourist visa, also known as a B-2 visa, applicants must demonstrate their eligibility and provide supporting documentation. This includes a valid passport, a completed online application form, proof of financial means to cover expenses, and a detailed itinerary of the planned activities while in the US. Additional US tourist visa requirements may include a letter of invitation, evidence of ties to the home country, and a medical examination. Applicants may need to attend an interview at a US embassy or consulate. It is crucial to carefully review and provide accurate and complete information to increase the likelihood of approval.
