Tourist visa stays are limited by your visa type and the permission the border officer grants

When you arrive at a US port of entry on a tourist visa, a Customs and Border Protection (CBP) officer decides how long you can stay. This is not determined by your visa itself. The officer stamps your passport with an I-94 arrival/departure record that shows your permitted stay length — typically 6 months for most countries, though it can be shorter. The visa in your passport only proves you were screened abroad; the I-94 is what actually controls your time in the US.

The most common tourist visas are the B-1/B-2 (business/tourist combined) and the B-2 (tourist only). Both allow the same stay length once you enter. The CBP officer has discretion to grant anywhere from a few days to 6 months, depending on what you tell them about your trip, how long you say you need, and their assessment of whether you plan to leave. If you say you need two weeks and the officer believes you, you may get exactly that — not the full 6 months.

Key Takeaways

  • The I-94 stamp in your passport, not your visa, controls how long you can stay; CBP officers at the border decide this length when you arrive.
  • Most tourists receive 6 months, but the officer can grant less if they believe your stated trip length or have concerns about your intent to leave.
  • You must leave by the date on your I-94; overstaying by even one day makes you deportable and bars future US entry.
  • If you need to stay longer, you must request an extension from USCIS before your I-94 date expires, though extensions are rarely granted for tourism.
  • Your I-94 expiration date is separate from your visa expiration date; a valid visa does not let you stay past your I-94 date.

What the I-94 stamp actually controls

The I-94 is a small white card (or digital record if you entered by air after 2013) that shows your name, passport number, arrival date, and departure date. That departure date is your hard important date. You are legally in the US only until midnight on that date. After that, you are overstaying, which triggers deportation proceedings and a permanent bar to future entry.

The CBP officer who stamps your I-94 is not reading from a chart. They are making a judgment call based on your answers to their questions: Why are you here? How long do you plan to stay? Where will you stay? Do you have a return ticket? Do you have ties to your home country — a job, family, property? If your answers are consistent and they believe you will leave, they typically grant 6 months. If you seem uncertain, evasive, or like you might stay longer, they can grant 30 days or 90 days instead.

The difference between your visa and your I-94

Many travelers confuse these two documents because they are both in your passport. Your visa is a stamp or sticker issued by a US embassy or consulate abroad. It proves you passed a background check and were approved to travel to the US. It does not control how long you stay. Your visa can be valid for 10 years, but that does not mean you can stay 10 years.

Your I-94 is issued when you cross the border. It is the actual permission to be in the US for a specific number of days. If your visa expires while you are in the US, that is fine — you can stay until your I-94 date. If your I-94 expires while your visa is still valid, you must leave. The I-94 date always controls.

How to find your I-94 expiration date

If you entered by air or sea after 2013, you do not have a physical card. Your I-94 is digital. You can look it up on the CBP website at cbp.gov/i94. You will need your passport number and date of birth. Write down the departure date listed there — that is your important date.

If you entered by land or before 2013, you have a physical I-94 card in your passport. It is a small white card with your information printed on it. The departure date is on the front. If you cannot find it, contact CBP at 1-877-CBP-5511 to request a replacement or to confirm your date.

Extending your stay beyond your I-94 date

If you need to stay longer than your I-94 allows, you must file a request for an extension with USCIS (US Citizenship and Immigration Services) before your I-94 date expires. You do this by mailing Form I-539, process to Extend/Change Nonimmigrant Status, to the USCIS office that covers your location. You can find the correct address on the USCIS website.

Extensions for tourism are rarely granted. USCIS assumes that if you needed more time, you should have asked the CBP officer for it at the border. Extensions are more commonly approved for people whose circumstances changed unexpectedly — a family member became ill, a business deal took longer than planned. You must show that the reason for the extension did not exist when you entered and that you still intend to leave.

Filing the extension does not automatically let you stay past your I-94 date. You can stay only if USCIS approves it before your date expires. If you file late or USCIS denies your request, you are overstaying and must leave when ready. Processing times for extensions vary, but you should expect at least 2 to 3 months.

What happens if you overstay

Overstaying your I-94 by even one day is a violation of US immigration law. You become deportable, meaning CBP or Immigration and Customs Enforcement (ICE) can arrest you and remove you from the country. You will be barred from returning to the US for at least 3 years (if you overstayed more than 180 days, the bar is 10 years). You will also have difficulty obtaining visas to other countries, because the US overstay will appear in your immigration record.

If you realize you have overstayed, do not wait. Contact an immigration attorney when ready. In some cases, you may be able to depart voluntarily, which is less damaging than being deported, though both result in a bar to future entry. Voluntary departure also gives you time to arrange your affairs before leaving.

Planning your trip to match your I-94

Before you arrive at the border, think about how long you actually need. If you plan a 3-week trip, tell the CBP officer that — do not ask for 6 months hoping to use it later. Officers are trained to spot travelers who request more time than they need, and it can raise suspicion. If you book a return flight, bring the confirmation. If you have a hotel reservation, bring that too. These documents help the officer believe your stated timeline.

If your plans change after you arrive and you need more time, do not straightforward stay past your I-94 date hoping no one notices. File the extension request when ready. If you realize you need to leave early, you can depart without penalty — there is no minimum stay requirement.

Frequently Asked Questions

Can I stay longer if my visa is valid for 10 years?

No. Your visa validity has no effect on how long you can stay. Your I-94 date is what controls. You could have a 10-year visa and still be required to leave after 6 months if that is what your I-94 says. The visa only lets you board a plane or enter at a border; the I-94 is your actual permission to be in the country.

What if I lose my I-94 card?

If you entered by air or sea after 2013, you do not need the physical card — your record is digital. Look it up at cbp.gov/i94. If you entered by land or before 2013 and lost the card, contact CBP at 1-877-CBP-5511 to request a replacement. You can also ask your local USCIS office for a copy of your arrival record.

Can the CBP officer change my I-94 date after I enter?

No. Once the officer stamps your I-94 at the border, that date is set. You cannot go back to the border and ask for more time. Your only option is to file an extension with USCIS before your date expires, and extensions for tourism are rarely approved.

Do I need to leave the US on the exact date on my I-94?

You must leave by midnight on that date. If your flight departs the next morning, you are overstaying. Book your departure for the same day as your I-94 expiration or earlier to be safe.

What if I want to change my trip and stay in a different city longer?

You can travel anywhere within the US during your I-94 period without permission. You do not need to notify anyone. Your I-94 date does not change based on where you are. If you need to stay past that date, file the extension request before it expires.
