At the port of entry
On arrival at any US port of entry, present passport and confirmed ESTA. CBP officers retain discretion to admit or refuse — the ESTA approval is a travel authorization, not a guarantee of admission. Biometric exit is now active at most major airports.
Customs and declarations
USD 10,000 cash declaration threshold on form FinCEN 105. Strict ban on most fresh produce, meat and dairy under USDA rules — declare all food on Form 6059B to avoid USD 300+ civil penalties.
Health and vaccinations
No general vaccination requirement; CDC may issue specific advisories during outbreaks.
Reasons travellers are refused entry
