This document provides information about the US visa application process. It discusses the types of visas available (non-immigrant for temporary visits, immigrant for permanent residence), how to obtain an appointment, required documents, common mistakes, and the interview process. The interview process typically involves completing an online application, paying fees, providing biometric data, and having an in-person interview to demonstrate eligibility for the visa. Applicants should bring original documentation and be prepared to demonstrate the purpose and validity of their trip. Visa processing times vary but usually take 5 days, though some cases may take longer. Denied applicants will be provided a refusal letter explaining the reasons for denial.
