Studying English as a Second Language (ESL) in the United States involves choosing from a wide variety of accredited programs offered by university language centers, community colleges, private language schools, and community-based organizations. Prospective students typically begin by identifying an institution certified by the Student and Exchange Visitor Program (SEVP), which is legally authorized to enroll international students. For intensive full-time programs, applicants must apply for and receive an F-1 student visa, which requires submitting proof of financial support, academic transcripts, and enrollment documentation. Alternatively, individuals visiting on tourist visas can enroll in recreational, part-time, or short-term courses that do not exceed specific credit and hour thresholds established by immigration regulations.
