Essential customs rules and
restrictions for entering USA
Traveler’s Guide by Parlaxy | Updated: August 14, 2025
Customs inspections at U.S. borders — whether at airports, land crossings with Canada or Mexico, or seaports — can range from quick document checks to full secondary inspections. Officers from U.S.
Customs and Border Protection (CBP) may review your luggage, hand-search personal items, inspect vehicles, and question you about your trip. Certain goods, like food, plants, animal products, and high-value electronics, often receive extra scrutiny. You are legally required to declare all items that exceed duty-free limits or fall under restricted categories, including gifts, currency over $10,000 USD, and commercial merchandise. Failure to declare – even by mistake – can result in immediate confiscation, on-the-spot fines, seizure of goods, or denial of entry. Always answer CBP questions truthfully, keep receipts for valuable items, and remember: if you’re unsure, declare it before crossing.

| Documents Required for Entry | Visa or ESTA Required As of 2025, most international travelers to the United States need either a visa or an ESTA (Electronic System for Travel Authorization), depending on nationality. Travelers from countries in the Visa Waiver Program (VWP), including much of Europe, Australia, New Zealand, Japan, and South Korea, can apply for ESTA for short visits (up to 90 days). Others must obtain a B-1/B-2 tourist or business visa in advance. ESTA (Visa Waiver Program) Eligible travelers must apply online for ESTA before boarding a U.S.-bound flight or cruise. Approval is usually quick, but last-minute applications can cause delays. ESTA is valid for two years or until your passport expires, whichever comes first, and covers multiple short-term visits. U.S. Visa If you’re not eligible for ESTA, you must apply for a visa at a U.S. embassy or consulate before traveling. This includes tourist (B-2), business (B-1), student, and work visas, each with specific requirements. Processing times vary, so apply well in advance of your trip. |
