Entering the United States for the first time can feel overwhelming — especially with strict border protection rules, immigration interviews, and documents required to enter USA. Whether you’re traveling for tourism, visiting family, or attending a business event, understanding US immigration rules will help you enter the country smoothly and avoid unnecessary delays.
This guide covers everything a first-time visitor needs to know before arriving in the USA.
Overview: What to Expect at US Immigration
All travelers — regardless of nationality — must pass through:
- Passport Control (CBP interview)
- Fingerprinting & Photo Capture
- Baggage Claim
- Customs Check
- Final Exit to Arrivals Hall
The key decision is made during passport control, where a CBP officer determines:
- Whether you can enter
- How long you can stay?
- What visa category you fall under?
1. Required Travel Documents at Immigration
When you arrive at the US border (airport or land), you must present:
- Valid passport
- ESTA (if VWP country) OR B1/B2 visa (everyone else) Which One Do You Need? Check out – ESTA vs B1/B2 Visa guide for full information.
- Return or onward ticket
- Proof of funds (if asked)
- Accommodation details
- Customs declaration form (CBP Form 6059B)
Missing or incomplete documents can lead to extra questioning or denial of entry.
2. US Immigration Interview (CBP) – What Happens
First-time visitors should expect a short interview lasting 1–3 minutes.
This is normal and part of standard entry procedures.
CBP officers typically ask:
- What is the purpose of your trip?
- How long will you stay?
- Where are you staying in the US?
- Do you have a return ticket?
- Who are you visiting?
- How much money do you have?
Answer honestly and confidently. Immigration officers look for:
✔ Clear travel purpose
✔ Strong ties to home country
✔ Sufficient funds
✔ No intention to work illegally
3. Biometric Screening (Fingerprints & Photo)
All first-time visitors (except some diplomats) must provide:
- Digital fingerprints
- A facial photo
This is routine and takes 30 seconds.
4. Length of Stay Is Decided at the Border
Even if your visa is valid for years, the CBP officer decides how long you can stay on each entry.
Typical maximum stays:
- ESTA → up to 90 days
- B1/B2 Visa → up to 6 months

- Mention plans to work in the US
- Carry large amounts of undocumented cash

- Provide inconsistent answers
- Lack proof of accommodation
- Have no return ticket
- Have previously overstayed in the US
Avoid volunteering unnecessary information — keep answers brief and factual.

Items you MUST declare:

There is no official minimum, but a safe guideline is:
$150–$200 per day of travel.
8. Accommodation Proof
Although not mandatory, it is useful to carry:
- Hotel booking
- Airbnb confirmation
- Host’s address (if staying with relatives)
If you cannot explain where you will stay → expect additional questioning.
