How long a visitor can stay depends on the visa type and what the border officer stamps in your passport

When you arrive at a US port of entry, a Customs and Border Protection officer will examine your documents and decide how long you can stay. For most visitors on a B-1/B-2 visa (business and tourism), the officer stamps an I-94 arrival/departure record into your passport or issues it electronically. That stamp shows your permitted stay length — commonly 6 months, but sometimes 3 months, 1 month, or even a specific number of days. The date on that stamp is what matters, not the expiration date of your visa itself.

You must leave by the date stamped in your passport. Staying past that date, even by one day, puts you in the US unlawfully and can affect future visa applications and re-entry. If you need more time, you can request an extension before your current permission expires, but the officer's initial decision is not automatic.

Key Takeaways

  • The border officer's stamp in your passport (or electronic I-94 record) sets your allowed stay length, not your visa expiration date.
  • Most B-1/B-2 visitors receive 6 months, but officers can grant less based on what they believe you need and your circumstances.
  • You must leave by the stamped date or request an extension through USCIS before that date arrives.
  • Overstaying by even one day makes you deportable and can bar you from future US visas and entry.
  • Some visa categories (like F-1 student visas) have different rules and are tied to your program end date, not a fixed stamp.

What the border officer decides at entry

The Customs and Border Protection officer at the airport, land border, or seaport has discretion to set your stay length. They look at your purpose (tourism, business meetings, visiting family), how long you say you need, your ties to your home country, and whether your documents are in order. If you tell them you are staying two weeks for vacation, they might stamp you for exactly that. If you say you are visiting family and have no clear end date, they might grant 6 months as a standard allowance.

The officer is not required to give you the maximum time. They can stamp you for a shorter period if they have concerns about your intent to return home. This decision happens in minutes at the border, and you do not get a formal hearing or appeal process at that moment. If you disagree with the length granted, your only option is to request an extension later through USCIS.

Standard stay lengths for common visa types

B-1/B-2 visitors (the most common tourist and business visa) typically receive 6 months, though 3 months is also common. Some officers grant shorter periods — 30 days, 60 days, or 90 days — depending on the circumstances. There is no fixed rule; it depends on the individual officer and what they believe is appropriate for your stated purpose.

Other visa categories have different rules. F-1 student visas are not stamped for a fixed number of months; instead, you are permitted to stay for the duration of your studies plus a grace period (usually 60 days after your program ends). J-1 exchange visitor visas work similarly — your stay is tied to your program dates, not a calendar stamp. H-1B work visas are valid for the length of your employment contract, up to 3 years initially. If you hold one of these visas, your allowed stay is not determined by a border stamp but by the terms of your visa category and your specific authorization document.

How to find your exact departure date

Look at your passport. The border officer should have stamped a date next to "Admitted Until" or written it on your I-94 form. That date is your important date. If you received an electronic I-94 (which is common for air and sea arrivals), you can look it up on the CBP website at cbp.gov/i94 using your passport number and date of birth. The I-94 record will show the exact date you must leave.

If you cannot find the stamp or the electronic record, contact USCIS or visit a local USCIS office with your passport. Do not guess or assume you have 6 months. An incorrect departure date can lead to overstay, which has serious consequences.

Requesting an extension before your time runs out

If you need to stay longer, you must file Form I-539 (process to Extend/Change Nonimmigrant Status) with USCIS before your current permission expires. You cannot extend your stay after the date has passed. The form costs a filing fee (currently $385 for most extensions, though fees vary) and requires supporting documents showing why you need more time — medical records if you are ill, a letter from a family member if there is a family emergency, or other evidence of your situation.

USCIS typically takes 2 to 6 months to decide an extension request. While your case is pending, you are allowed to stay in the US even if your original date has passed, as long as you filed before the important date. However, if USCIS denies your extension, you must leave when ready. Filing an extension does not may provide approval.

What happens if you stay past your departure date

Overstaying — remaining in the US past your permitted departure date — makes you deportable. Even one day over the limit counts. If you overstay, you lose your legal status, and immigration enforcement can detain and remove you. An overstay also creates a bar to future US visas: if you overstay by more than 180 days, you are barred from re-entering the US for 3 years; if you overstay by more than 1 year, you are barred for 10 years.

Additionally, an overstay can affect your ability to sponsor family members for visas, your may be able to access for certain immigration benefits, and your credibility in any future immigration proceedings. Even if you leave voluntarily after overstaying, the bar still applies. The consequences are severe, so it is critical to track your departure date and either leave on time or file an extension before the important date.

Special rules for certain visa categories

Some visas do not work on a straightforward "admitted until" date. F-1 students are admitted for the duration of their studies (called "duration of status"), which means as long as you are enrolled full-time and following the rules of your program, you can stay. Your I-20 form (issued by your school) shows your program end date, and you have a 60-day grace period after that to prepare to leave or transfer to another school. You do not have a fixed departure date stamped in your passport.

J-1 exchange visitors (scholars, interns, trainees) also stay for the duration of their program plus a grace period. Your DS-2019 form shows your program dates. H-1B workers stay for the length of their employment authorization, which is initially up to 3 years and can be extended. If you hold one of these visas, your stay length is not set by a border stamp but by your program or employment documents.

Frequently Asked Questions

Can I stay longer if my visa is still valid?

No. Your visa expiration date and your allowed stay length are separate. A visa that does not expire until 2026 does not let you stay past the date the border officer stamped in your passport. The stamp is what controls how long you can remain in the US.

What if the border officer did not stamp my passport?

If you arrived by air or sea, you should have an electronic I-94 record. Check it at cbp.gov/i94. If you arrived by land and have no stamp and cannot find an electronic record, contact USCIS when ready to clarify your status. Do not assume you can stay indefinitely.

Can I leave and come back to reset my stay?

Leaving and re-entering can restart your stay, but it is risky. If the border officer suspects you are trying to circumvent the system (called "visa runs"), they can deny you entry or grant a much shorter stay the next time. It is safer to request an extension if you need more time.

Do I need to leave on the exact date or can I leave a few days early?

You can leave any time before your departure date. Leaving early does not cause problems. You only violate the rules if you stay past the date.

What if I am sick or have an emergency on my departure date?

If you cannot leave due to a medical emergency or other urgent circumstance, contact USCIS or an immigration attorney when ready. You may be able to file an emergency extension or request a brief stay while you address the situation. Do not straightforward stay without authorization — contact USCIS first.
