1. Valid Passport (Mandatory for All Travelers)
To enter the USA, your passport must meet two requirements:

(Unless your country is part of the Six-Month Club where this rule is waived.)
Most travelers entering the US use:
- Standard passports (tourists)
- ePassports (with chip symbol)
Tip: Avoid using damaged or nearly expired passports — it may cause denial at the airport.
2. Visa or ESTA Authorization
Depending on your nationality, you must have either:
A) ESTA Authorization (Visa Waiver Travelers)
If you’re from a Visa Waiver Program (VWP) country (e.g., UK, Germany, Australia, Japan), you must apply for an ESTA before boarding your flight.
ESTA Requirements:
- Valid passport from a VWP country
- Approved ESTA application
- Stay up to 90 days
- Purpose: tourism, business, or transit
ESTA is valid for 2 years and allows multiple entries.
B) B1/B2 Tourist Visa (Non-VWP Travelers)
Citizens of countries like:
- India
- Philippines
- China
- South Africa
- Pakistan

Required documents for B1/B2 visa entry:

3. Return or Onward Travel Ticket
While not always mandatory, US immigration officers frequently ask for proof you plan to leave the US.
Proof can include:
- Return flight ticket
- Onward ticket to another country
- itinerary showing departure date
Travelers arriving without this may be questioned or denied entry.
4. Proof of Funds (For Immigration Check)
CBP officers may request proof you can financially support your trip.
Acceptable proof includes:
- Recent bank statements
- Credit cards
- Cash
- Sponsorship letter (if someone is hosting you)
There is no fixed minimum amount, but typically:
$150–$200 per day is considered sufficient.
5. Accommodation Details
Not mandatory, but helpful during immigration questioning.
Examples:
- Hotel booking
- Airbnb reservation
- Invitation letter with host’s address
- Tour package confirmation
Even a temporary booking greatly reduces questioning time.
6. Travel Itinerary
A simple itinerary helps immigration understand your travel plans.
It may include:
- Cities you will visit
- Tourist attractions
- Internal flights
- Road trips
- Hotel locations
A clear plan shows you are a genuine tourist.
7. Travel Insurance (Highly Recommended)
Travel insurance is not mandatory for entering the USA.
However, because healthcare in the United States is extremely expensive:
- A doctor visit can cost $200–$500
- Emergency care can exceed $10,000
Most airlines, embassies, and travel experts recommend having coverage.
8. Customs Declaration Form (CBP Form 6059B)
Every traveler must complete a customs declaration upon arrival to declare:
- Food items
- Cash over $10,000
- Gifts

Most airlines provide the form on the plane, or you can complete it digitally at kiosks.
