Your stay length depends on your visa type and what the immigration officer stamps in your passport

The length of time you can stay in the USA is not determined by your visa alone. Your visa gets you to the border; the admission stamp in your passport determines how long you can remain. A tourist visa might say you can enter, but the officer at the airport decides whether you stay 30 days or 180 days. Different visa categories have different maximum stays, and some allow extensions while others do not.

The document you receive at entry is called the I-94 arrival/departure record. This shows your admission date and your authorized stay period — the date by which you must leave or change your status. Overstaying this date, even by one day, creates legal problems for future visas and entry to the USA.

Key Takeaways

  • Tourist visas (B-1/B-2) typically allow stays of 6 months, but the officer at entry decides the actual length, which may be shorter.
  • Work visas (H-1B, L-1, O-1) are tied to your employment and usually last as long as your job authorization, often 3 to 6 years with extensions.
  • Student visas (F-1) allow you to stay for the duration of your program plus a grace period, which can be 4 to 6 years or longer.
  • You can request an extension before your authorized stay ends, but approval is not may provide and depends on your visa category.
  • Your I-94 record shows your exact departure date; check it when ready after entry because errors are common and difficult to fix later.

Tourist and visitor visas: what the 6-month rule actually means

A B-1/B-2 tourist visa is valid for 10 years (or 6 years for some nationalities), but that validity period is not your stay length. When you arrive, the officer stamps your passport with an admission date and a departure date. Most officers grant 6 months, but they can grant less — 30 days, 90 days, or any period they choose. There is no way to predict what length you will receive.

The officer bases the decision on your answers about why you are visiting, how long you said you would stay, whether you have ties to your home country, and your travel history. If you say you are visiting for two weeks but your passport shows you stayed 6 months on your last visit, the officer may grant only 30 days this time.

You cannot extend a tourist visa while in the USA. If your authorized stay ends and you want to remain longer, you must leave and reapply for a new visa. Requesting an extension is possible only in narrow circumstances — a medical emergency that prevents travel, for example — and requires filing with USCIS before your departure date.

Work visas: duration tied to your job authorization

Work visas come in many categories — H-1B (specialty occupation), L-1 (intracompany transfer), O-1 (extraordinary ability), E-2 (treaty investor) — and each has different maximum stays. An H-1B visa is typically valid for 3 years and can be extended for another 3 years, for a total of 6 years. An L-1 visa can be granted for up to 7 years depending on whether you are a new employee or transferee. An O-1 visa is granted in 1-year increments and can be extended as long as you maintain your status.

Your stay length is controlled by your I-797 approval notice, which your employer receives from USCIS. This document shows the dates your work authorization is valid. You can stay only as long as you are employed and your authorization has not expired. If you change jobs, your authorization may end, and you must either transfer your visa to a new employer or leave the country.

Extensions are filed by your employer before your current authorization expires. The process takes several months, so your employer must begin the paperwork well in advance. If the extension is denied, your authorized stay ends on the date shown in your current approval notice.

Student visas: your stay covers your program plus a grace period

An F-1 student visa allows you to stay for the duration of your academic program. Your school issues an I-20 form that shows your program start and end dates. You are authorized to stay until the end date on that form, plus a grace period of 60 days after your program ends. During that grace period, you can prepare to leave or explore for a change of status (such as switching to an H-1B work visa).

If your program is a 4-year bachelor's degree, your I-20 will show an end date 4 years from your start date. If you then pursue a master's degree at the same school, your school issues a new I-20 with a new end date. Your total stay could be 6 years or longer if you stack multiple degrees.

You cannot extend your F-1 status beyond your program end date plus 60 days. If you want to remain in the USA after that period, you must change to a different visa category — usually H-1B — before the grace period ends. Your school's international student office can advise you on the timeline and process.

Family-based visas: when ready relatives versus preference categories

If you are a spouse, parent, or child of a US citizen, you are an when ready relative and can stay indefinitely once you are admitted as a permanent resident (green card holder). Your stay is not limited by a date; you can remain in the USA as long as you maintain your green card status and do not commit crimes that trigger deportation.

If you are a relative of a US citizen or permanent resident but not in the when ready relative category — for example, a sibling or adult child — you fall into a preference category. The wait time to immigrate can be many years, and during that wait you may be in the USA on a temporary visa (such as a tourist visa) with a limited stay. Once you are approved for permanent residency, your stay becomes indefinite.

What happens if you overstay your authorized departure date

Staying in the USA past your authorized departure date is a violation of immigration law, even if you overstay by one day. The consequences include ineligibility for future visas, deportation, and a bar on re-entry for 3 to 10 years depending on how long you overstayed. An overstay of more than 180 days triggers a 3-year bar; more than 1 year triggers a 10-year bar.

If you realize you will overstay, you can file for an extension or a change of status before your departure date ends. Filing before the important date stops the clock on the overstay violation, though approval is not may provide. Once your departure date has passed, you cannot file for an extension; your only option is to leave when ready or face deportation proceedings.

Check your I-94 record online at the US Customs and Border Protection website when ready after you arrive. Errors on the record — a wrong departure date, for example — are common. If you find an error, contact CBP to correct it before the date passes.

How to find your exact authorized stay dates

Your authorized stay dates are recorded in two places: your passport (the admission stamp) and your I-94 arrival/departure record. The I-94 is the official document; your passport stamp is a backup. You can view your I-94 online at cbp.gov/i94 by entering your passport number, date of birth, and passport country. The record shows your admission date and your departure date — the last day you are authorized to stay.

If you cannot find your record online, contact the CBP at the port of entry where you arrived. Bring your passport and any documents related to your visa category. Getting a copy of your I-94 is free and usually takes a few days by mail.

If your I-94 shows an incorrect departure date, file a correction request with CBP when ready. Do not wait until the date is close; errors can take weeks to fix, and you cannot extend your stay while a correction is pending.

Extensions and changes of status: when you can stay longer

Some visa categories allow extensions; others do not. Tourist visas cannot be extended except in emergencies. Work visas can be extended if your employer files before your current authorization expires. Student visas cannot be extended beyond your program end date plus 60 days, but you can change to a different visa category.

A change of status means switching from one visa category to another while remaining in the USA. For example, you might change from F-1 student status to H-1B work status. The change must be filed before your current authorized stay ends. If the change is approved, your new authorized stay period begins on the approval date.

Extensions and changes of status are filed with USCIS, not with the State Department. Processing times vary from a few weeks to several months. Your employer or school can help you file, or you can file on your own if you are may be able to access. Filing before your departure date is critical; filing after the date has passed disqualifies you from most forms of relief.

Frequently Asked Questions

Can I stay longer than my I-94 says if I file for an extension before the date?

Filing before your departure date stops the overstay clock, meaning you can remain in the USA while your extension or change of status is being reviewed. However, approval is not may provide. If your request is denied, you must leave by the original departure date shown on your I-94. Work with an immigration attorney or your employer to understand whether an extension is possible for your visa type.

What if I lose my passport and can't find my admission stamp?

Your I-94 record is the official proof of your authorized stay, not your passport stamp. You can retrieve your I-94 online at cbp.gov/i94 or request a copy from CBP by mail. When you renew your passport, the new passport will not have the original admission stamp, but your I-94 record will still show your authorized dates. Bring a copy of your I-94 when you travel outside the USA and return.

Can I request a longer stay at the airport when I arrive?

You can tell the officer at entry how long you plan to stay, and some officers will grant longer periods if you explain your reasons. However, the officer has complete discretion and can grant any length they choose, including less than you requested. There is no appeal process; the officer's decision is final. Plan your trip conservatively and request only the time you genuinely need.

If I marry a US citizen while on a tourist visa, can I stay longer?

Marriage to a US citizen does not automatically extend your tourist visa or change your authorized stay. You must file for a change of status to permanent resident (green card) before your departure date ends. The process takes several months. If you file before your departure date, you can remain in the USA while your process is reviewed. Consult an immigration attorney before marrying to understand the timeline and requirements.

What counts as overstaying if I leave on my departure date?

You must leave by the end of the day shown on your I-94. If your departure date is January 15, you can leave anytime on January 15 and not overstay. If you leave on January 16, you have overstayed by one day. Some airlines require you to check in the day before departure, so book flights that depart on or before your authorized departure date, not after.
