United States ESTA, Visa Waiver Program, visitor visas, I-94 and customs declarations
Use CBP and State Department sources for ESTA, the Visa Waiver Program, visitor visas, Form I-94 and admission records. USA.gov gives a current plain-English official summary of Visa Waiver/ESTA and related visitor documents.
Use CBP customs pages for declarations, duty information, prohibited/restricted goods and traveller arrival/customs procedures. Air and sea Visa Waiver travellers use ESTA; land and selected ferry arrivals may need provisional I-94.
