Your Visitor Stay Length Depends on Your Entry Document
How long you can stay in the USA as a visitor depends on what document you entered with and what a U.S. Customs and Border Protection officer wrote in your passport when you arrived. Most visitors on a tourist visa or visa waiver get permission to stay for 6 months, but some receive 3 months or less. A cruise passenger might get 1 day. The officer's stamp or notation — not the visa itself — controls your actual important date.
The I-94 arrival record is the official document that shows your permitted stay length. This record is now electronic for most visitors and is linked to your passport number. You can view your I-94 online at the U.S. Customs and Border Protection website using your passport number and date of birth. Write down the "Admitted Until" date the moment you see it, because that is your hard important date for leaving the country.
Key Takeaways
- Your stay length is determined by the CBP officer at entry, not by your visa type, and is recorded on your I-94 arrival record.
- Most tourist visa holders receive 6 months, but officers can grant 3 months, 1 month, or even shorter periods at their discretion.
- You must leave by the "Admitted Until" date on your I-94 or you will be considered overstaying, which triggers deportation proceedings and bars future entry.
- You can request an extension before your date expires, but extensions are rarely granted and require a strong reason unrelated to tourism.
- Staying past your date by even one day is a violation; there is no grace period and no way to "fix it" after the fact.
Finding Your Exact Departure important date
Go to the CBP's I-94 website at cbp.gov/i94 and enter your passport number, passport country, and date of birth. The system will display your arrival record with the exact date you must leave. This date is printed in the format MM/DD/YYYY. If you cannot access the online system, call the CBP Information Line at 1-877-CBP-5511, though wait times are often long.
If you entered the USA before the I-94 system went fully electronic, you may have a physical I-94 card in your passport. Check the back of the card for the "Admitted Until" date. If you cannot find your I-94 record online and do not have a physical card, contact the CBP at the port of entry where you arrived and request a copy of your arrival record.
What Happens If You Overstay Your Visitor Period
Staying in the USA past your "Admitted Until" date is a violation of federal immigration law. You do not need to be arrested or caught to be considered an overstayer — the violation exists the moment the clock strikes midnight on your important date. Immigration and Customs Enforcement (ICE) can initiate deportation proceedings against you, and you will be placed in removal proceedings in immigration court.
An overstay also bars you from returning to the USA for years. If you overstay by more than 180 days, you are barred from re-entry for 3 years. If you overstay by more than 1 year, you are barred for 10 years. Even a 1-day overstay can result in a ban, though shorter overstays are sometimes overlooked if you leave voluntarily and when ready. There is no grace period, no forgiveness, and no way to "fix" an overstay after it happens.
Requesting an Extension Before Your Date Expires
You can request an extension of your stay by filing Form I-539 (process to Extend/Change Nonimmigrant Status) with U.S. Citizenship and Immigration Services (USCIS) before your current "Admitted Until" date passes. You must file at least 45 days before your important date, though filing earlier is safer. The filing fee is currently $685, and USCIS will send you a receipt notice that gives you temporary permission to stay while your request is being reviewed.
Extensions are rarely granted for tourism reasons. USCIS approves extensions when you have a legitimate, unforeseen reason to stay longer — a serious family illness, a legal proceeding you are involved in, or a job offer that requires you to change status. straightforward wanting more vacation time or not being ready to leave will not result in approval. If USCIS denies your extension and your original date has already passed, you become an overstayer when ready.
Changing Your Status While in the USA
If you want to stay longer than your visitor period allows, you may be able to change to a different visa status while you are in the USA — for example, from a tourist to a student visa or work visa. This process is called status adjustment and requires filing Form I-539 or a status-specific form (like Form I-539 for a student visa change, or Form I-129 for a work visa).
You must file your status change request before your current "Admitted Until" date expires. Once you file, you receive a receipt notice that allows you to stay in the USA while USCIS reviews your request, even if your original date passes. However, if your request is denied, you revert to overstayer status when ready. Status changes are complex and often require an immigration attorney to navigate correctly.
Leaving the USA Before Your important date
You must physically depart the USA by 11:59 p.m. on your "Admitted Until" date. Leaving on a flight that departs after midnight counts as overstaying, even if you are already at the airport. If you are unsure of your exact important date, leave at least one day early to be safe.
When you leave, CBP will scan your passport and confirm your departure in the system. Keep your boarding pass and any exit documentation for your records. If you plan to return to the USA in the future, leaving on time and not overstaying is the single most important factor in being admitted again.
Visitor Stays for Canadians and Mexicans
Canadian citizens do not need a visa to visit the USA and are admitted as visitors without a visa. A Canadian's stay length is determined the same way — by the CBP officer at entry and recorded on an electronic I-94. Most Canadians receive 6 months, but the officer can grant less.
Mexican citizens and citizens of other countries must have a valid visa or be part of the visa waiver program. The rules for stay length are the same regardless of nationality: the officer's decision at entry controls your important date, not your visa type.
Frequently Asked Questions
Can I stay longer than 6 months if I keep leaving and re-entering the USA?
No. CBP officers are trained to spot this pattern, called "visa runs," and will deny entry if they believe you are trying to circumvent the visitor limit. Each entry is independent, but officers have access to your full entry history and can refuse admission if your pattern suggests you are living in the USA rather than visiting.
What if I lose my passport before my departure date?
Contact your country's embassy or consulate in the USA when ready to report the loss and request an emergency travel document. You will need this document to leave the USA. Do not delay — obtaining a replacement can take days or weeks, and you must leave by your important date regardless.
Do I need to notify anyone that I am leaving on my departure date?
No formal notification is required. CBP will record your departure automatically when you check in for your flight or cross a land border. Keep your boarding pass or exit documentation in case you need proof later that you left on time.
Can I work while I am a visitor in the USA?
No. Visitor status does not permit employment. Working while on visitor status is a violation and can result in deportation and a bar to future entry. If you want to work in the USA, you must change to a work visa status before you begin working.
What if my flight is delayed and I cannot leave by my important date?
Contact CBP or your airline when ready. A flight delay beyond your control may be considered a valid reason for a brief overstay, but you must document the delay and report it. Do not straightforward miss your flight and hope for forgiveness — proactively contact the authorities and explain the situation.
