ESL / ELL support
US public schools must support students learning English. At enrolment families complete a Home Language Survey and an English assessment decides the support. Ask the district about its programmes.
F-1 student visas cannot be used for US public elementary or middle schools (K-8); public high school on an F-1 is limited to 12 months with full tuition paid (US Department of State). Your status depends on the parents' visa, so confirm with official sources.
