How Long You Can Stay as a Visitor
The length of time you can stay in the United States as a visitor depends on the visa type you hold and the decision made by the U.S. Customs and Border Protection officer when you arrive. Most visitors on a B-1/B-2 visa (business and tourism) receive permission to stay for up to six months, though the officer can grant less time. The exact duration is written on your I-94 arrival/departure record, which you receive when you enter the country. This is not the same as your visa expiration date — your visa only proves you were cleared to enter; the I-94 controls how long you can remain.
If you arrive without a visa under the Visa Waiver Program (citizens of about 40 countries, including most of Europe, Australia, and Japan), you typically receive 90 days. That 90-day clock starts the moment you are admitted and cannot be extended. Other visa categories — student visas, exchange visitor visas, work visas — have their own rules and are covered separately in visa-specific guides.
Key Takeaways
- Your I-94 arrival record, not your visa, determines how long you can stay; the officer at the border decides the length when you arrive.
- B-1/B-2 visitors usually receive up to six months, but the officer can grant less based on your answers and documents.
- Visa Waiver Program visitors receive exactly 90 days and cannot extend that period.
- Staying past your I-94 expiration date makes you out of status and can affect future travel to the United States.
- You can request a shorter stay when you arrive if you know you will leave earlier.
What the Officer Decides at the Border
When you arrive at a U.S. port of entry, a Customs and Border Protection officer interviews you and decides how long to let you stay. The officer looks at your purpose (tourism, visiting family, business meetings), how much money you have, whether you have ties to your home country, and your travel history. If you say you are staying two weeks but have no hotel reservation and no return ticket, the officer may grant only 30 days. If you present a clear itinerary, a return flight, and proof of funds, you are more likely to receive the full six months.
The officer writes the authorized stay period on your I-94 form. You can ask the officer to grant you less time if you know you will leave sooner — for example, if you are only staying three weeks, you can request 30 days instead of six months. Some visitors do this to avoid overstaying by accident.
The Difference Between Your Visa and Your I-94
Your visa is a stamp or document in your passport that says the U.S. State Department cleared you to travel to the United States. It does not say how long you can stay. A B-1/B-2 visa is often valid for 10 years, but that does not mean you can stay for 10 years — it only means you can use that visa to enter the country multiple times during those 10 years.
Your I-94 is what controls your actual stay. It is a record created when you arrive, and it shows your admission date and your departure date (the last day you are allowed to be in the country). You can view your I-94 online through the U.S. Customs and Border Protection website using your passport number. If you lose your I-94 card, you can still access this information online and print it if needed.
Extending Your Stay
If you are on a B-1/B-2 visa and your I-94 expires before you are ready to leave, you can file a request to extend your stay. You must file Form I-539 (process to Extend/Change Nonimmigrant Status) with U.S. Citizenship and Immigration Services before your current I-94 expires. The extension is not automatic — you must show that your circumstances have changed or that you have a valid reason to stay longer.
Extensions are granted at the discretion of USCIS and can take several weeks to process. While your extension is pending, you are allowed to remain in the United States, but you should not leave the country — doing so may cancel your pending request. Visa Waiver Program visitors cannot extend their 90-day stay under any circumstances; if you need more time, you must leave and re-enter, though doing so repeatedly can raise suspicion.
What Happens If You Overstay
Staying in the United States past your I-94 expiration date puts you out of status. This means you are no longer legally present. Even one day past your authorized departure date counts as overstaying. Being out of status can result in deportation proceedings, a ban on future entry to the United States, and difficulty obtaining visas to other countries.
If you overstay by more than 180 days, you trigger an automatic bar that prevents you from returning to the United States for three years. If you overstay by more than one year, the bar is 10 years. These bars explore even if you leave voluntarily. The only way to clear an overstay bar is to file a waiver, which is difficult and expensive. Leaving on time is far simpler than dealing with the consequences of overstaying.
Checking Your I-94 and Departure Date
You should check your I-94 as soon as you receive it or shortly after you arrive. Go to the U.S. Customs and Border Protection website (cbp.gov) and use the I-94 lookup tool. Enter your passport number, passport country, and date of birth. The system will show your admission date, your authorized departure date, and your visa class. Print or save this information in case you need to show it to an employer or landlord.
If the date on your I-94 is wrong — for example, if it says you must leave in 30 days but you were told 90 days — contact CBP or the nearest USCIS office to request a correction. Errors do happen, and it is better to fix them early than to discover a problem when you are trying to leave.
Staying Longer: Changing Your Visa Status
If you want to stay in the United States longer than your visitor visa allows, you may be able to change your status to a different visa category — for example, from B-2 (tourist) to F-1 (student) if you are accepted to a school, or to H-1B (specialty occupation worker) if an employer sponsors you. Status changes are handled through USCIS and require filing additional forms and meeting new requirements.
You must file your status change request before your current I-94 expires. While your request is pending, you can remain in the United States in valid status. However, status changes are complex and often require legal help. If you are considering this option, speak with an immigration attorney or a may have access to immigration consultant before your visitor status is about to end.
Frequently Asked Questions
Can I stay longer than six months if I keep leaving and coming back?
Technically yes, but U.S. immigration officers track your pattern of entries and exits. If you repeatedly enter on a B-1/B-2 visa, stay six months, leave for a few days, and return, officers may suspect you are trying to live in the United States on a visitor visa. They can deny you entry or grant you a much shorter stay. This pattern can also affect your ability to get other visas in the future.
What if I want to work while I am visiting?
You cannot work on a B-1/B-2 visitor visa. Working without authorization puts you out of status when ready, even if you are paid under the table. If you need to work in the United States, you need a work visa such as H-1B, L-1, or O-1. Speak with an immigration attorney about your options before you start any job.
Do I need to leave the country before my I-94 expires?
Yes. You must depart the United States on or before the date shown on your I-94. If you are on a flight that lands after midnight on your departure date, you are overstaying. Plan your departure carefully and leave with time to spare.
Can I get my I-94 extended if I am sick or have an emergency?
You can file Form I-539 to request an extension for humanitarian purposes or other compelling reasons, but approval is not may provide. You must file before your current I-94 expires. If you have a medical emergency, contact USCIS as soon as possible to explain your situation.
What happens to my I-94 if I leave early?
Your I-94 is cancelled when you depart the United States. Leaving early does not cause any problems — you are allowed to leave whenever you want, as long as it is before your authorized departure date. You do not need permission to leave early.
