Tourist stay length depends on your visa type and entry status
How long you can stay in the US as a tourist depends on what document you entered with. Most tourists arrive on a B-2 visa or visa waiver and receive a stamp in their passport at the border that says how long they can stay — usually six months, but sometimes less. That stamp is your legal limit. If you overstay it, even by one day, you become deportable and may face a ban on returning to the US.
The officer at the border decides your length of stay when you arrive, not before. They look at your return ticket, bank statements, ties to your home country, and the reason for your visit. You cannot negotiate this in advance, and the length they give you is not a suggestion — it is a legal important date.
Key Takeaways
- The US Customs and Border Protection officer stamps your passport with an expiration date when you enter; that date is your legal important date to leave.
- Most B-2 tourists receive six months, but officers can grant less if they doubt your intent to return home.
- Visa waiver visitors (from countries like Canada, UK, Australia, and 37 others) get the same length of stay as B-2 visa holders but do not need a visa before arrival.
- Overstaying by even one day can result in deportation proceedings and a ban on future US entry.
- You can request an extension through USCIS before your date expires, but approval is not may provide and takes weeks.
What the border officer writes in your passport
When you pass through US Customs and Border Protection at the airport or land border, the officer stamps your passport with two dates: the date you arrived and the date you must leave. The second date is written as "D/S" (duration of status) or a specific date like "06/15/2025". That date is your legal important date. You must leave the US by midnight on that day or you are in violation of US immigration law.
The officer decides this length based on what you tell them and what documents you show. They may ask how long you plan to stay, where you are going, whether you have a return ticket, and whether you have family or a job waiting for you at home. If they believe you might stay longer than you say, or if they think you might work illegally, they can give you a shorter period — sometimes as little as 30 days. You cannot appeal this decision at the border.
The stamp in your passport is the only official record of your allowed stay. Keep your passport safe and do not lose it. If your passport is lost or stolen while you are in the US, you will need to contact your country's embassy or consulate to get a replacement, and you will need to show the replacement to US authorities before you leave.
B-2 tourist visas versus visa waiver entry
A B-2 visa is a document you obtain from a US embassy or consulate in your home country before you travel. It says the US government has reviewed your background and approved you to visit. When you arrive at the US border with a B-2 visa, the officer still stamps your passport with a stay length — usually six months — but the visa itself does not expire on that date. The visa can be valid for 10 years or more. What matters is the stamp in your passport, not the visa.
A visa waiver means you do not need a visa at all. Citizens of 41 countries, including Canada, the UK, Australia, Japan, South Korea, and most of Western Europe, can enter the US for tourism without explore for a visa first. Instead, you register online through ESTA (Electronic System for Travel Authorization) before you board your flight. ESTA costs $14 and is valid for two years. When you arrive at the border, the officer stamps your passport just as they would for a B-2 visa holder — usually for six months. The length of stay is the same either way.
The main difference is timing and cost. A B-2 visa requires an appointment at an embassy, an interview, and processing time — sometimes weeks or months. A visa waiver requires only an online form and takes minutes. But both result in the same thing: a stamp in your passport that tells you when you must leave.
What happens if you stay past your expiration date
Overstaying your allowed time in the US is a civil violation, not a criminal one, but the consequences are serious. If you stay even one day past the date in your passport, you are deportable. US Immigration and Customs Enforcement (ICE) can detain you, and you will face removal proceedings in immigration court. You will be ordered to leave the country and may be banned from returning for three years, ten years, or permanently, depending on how long you overstayed.
An overstay also affects your future travel. If you overstay and then leave the US on your own, you will have a record of the violation. If you later try to return — even years later — the border officer will see the overstay and may deny you entry. If you try to sponsor a family member for immigration, your overstay will count against you. If you try to become a permanent resident, an overstay can disqualify you.
The US government tracks your entry and exit through the US-VISIT system. When you leave the US, your departure is recorded. If your departure date is after the date in your passport, the system flags you as an overstay. There is no grace period and no way to "fix" an overstay after the fact except by leaving the country when ready.
Extending your stay before the important date
If you want to stay longer than the date in your passport, you must request an extension before that date arrives. You do this by filing Form I-539, process to Extend/Change Nonimmigrant Status, with US Citizenship and Immigration Services (USCIS). You must file it at least 45 days before your expiration date, though filing earlier is safer.
An extension is not automatic. USCIS will review your reason for staying longer — tourism, visiting family, medical treatment — and your financial situation. They will check whether you have ties to your home country and whether you have followed the rules so far. If they approve your extension, they will send you a notice and stamp your passport with a new date. If they deny it, you must leave by your original date.
The process takes weeks, sometimes months. You should not plan on an extension being approved quickly. If you file an extension and it is still pending when your original date expires, you are technically in violation while you wait for a decision, though USCIS guidance says you are not deportable while a pending extension is being decided. Do not rely on this — file early and have a backup plan to leave if the extension is denied.
Staying longer through a change of status
If you want to stay in the US longer than a tourist visit allows, you can change your immigration status while you are here — but only if you have a sponsor and meet the requirements for a different visa category. For example, if you fall in love with someone in the US, they can sponsor you for a fiancé visa or marriage-based green card. If a US employer wants to hire you, they can sponsor you for an H-1B work visa. If you want to study, you can change to an F-1 student visa.
A change of status requires filing a petition with USCIS and meeting strict requirements. You cannot straightforward decide to stay and work or study. Your employer or school or family member must file the petition on your behalf, and you must be in the US legally when they file. Once the petition is approved and your new status begins, your old tourist status ends and your new status rules explore.
This process is complex and takes months. You should consult an immigration attorney if you think you might want to change status. Attempting to change status without proper sponsorship or filing can result in deportation.
What to do before your stay ends
About two weeks before your expiration date, you should book your departure flight or arrange your travel to the border. Keep your airline ticket or travel confirmation with you. When you leave the US, you will pass through US Customs and Border Protection again, and they will check your passport to confirm you are leaving on time.
If you are driving to Canada or Mexico, you will pass through a land border checkpoint. Have your passport ready. The officer will scan it and confirm your departure. If you are flying out, you will check in at the airline counter, and they will scan your passport before you board. The airline will not let you board if your stay has expired.
Do not try to stay past your date. Do not assume the government will not notice. Do not plan to leave "soon" — leave by the date in your passport. If you have questions about your date or whether you can extend, contact USCIS or your country's embassy in the US before your important date arrives.
Frequently Asked Questions
Can I stay longer if I have a return ticket booked after my expiration date?
No. Your expiration date is set by the border officer when you arrive, not by your ticket. If your ticket is after your expiration date, you must change it or request an extension before the date expires. Traveling on an expired status is a violation.
What if I lose track of my expiration date?
Check your passport when ready. The date is stamped on the page where your entry was recorded. If you cannot find it or your passport is damaged, contact your country's embassy or consulate. They can help you determine your status and what to do next.
Can I extend my stay by leaving and coming back?
No. If you leave the US and try to return, the border officer will see your previous overstay or your recent departure and may deny you entry. Leaving and returning is not a way to reset your time.
Do I need to notify anyone when I leave?
No formal notification is required. Your departure is recorded automatically when you pass through US Customs and Border Protection at the airport or border. Keep your passport with you and present it when asked.
What if I am sick or injured and cannot leave by my date?
Contact USCIS or your country's embassy when ready. Medical emergencies may be grounds for an extension, but you must request it before your date expires. Do not wait until after you have overstayed.
