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

The length of stay is not determined by your visa category alone. When you arrive at a US port of entry, a Customs and Border Protection officer examines your documents and stamps an arrival/departure record (Form I-94) into your passport or issues it electronically. That stamp shows your permitted stay duration — typically written as a date by which you must leave. A tourist visa might allow 6 months; a student visa might allow the duration of your program plus 60 days. The visa itself is only permission to board a plane or ship to the US; the stamp is what actually controls how long you can remain.

If no duration is written, you are generally permitted to stay for the validity of your visa, but this is rare. Most visitors receive a specific departure date. Overstaying that date, even by one day, makes you deportable and can bar you from returning to the US for years.

Key Takeaways

  • The arrival/departure stamp in your passport, not your visa, determines how long you can stay — check it when ready after entry.
  • Tourist visas (B-1/B-2) typically allow stays of 6 months, but the officer can grant less based on your documents and answers.
  • Student visas (F-1) permit you to stay for the duration of your program plus a grace period, usually 60 days after graduation.
  • Work visas (H-1B, L-1, O-1) limit your stay to the validity period of your petition, which your employer must renew if you want to extend.
  • Overstaying by even one day can result in deportation proceedings and a bar to re-entry for 3 to 10 years.

Tourist and visitor visas (B-1/B-2): typical stay of 6 months

A B-1/B-2 visa is the most common visa for people entering the US to visit family, attend conferences, or conduct business meetings. The visa itself does not specify a stay length. Instead, when you arrive, the CBP officer decides how long to permit you to remain based on your documents, your stated purpose, and their assessment of whether you intend to return home.

Most officers grant 6 months (180 days) for B-2 visitors. However, the officer can grant less — sometimes as little as 30 days — if they have concerns about your ties to your home country, the purpose of your visit, or your financial ability to support yourself. The date stamped in your passport is binding. If the officer writes "6 months from date of entry," you have 6 months. If they write a specific date, that date is your important date.

You cannot extend a B-2 stay by filing a form; you must leave and re-enter, or file Form I-539 (process to Extend/Change Nonimmigrant Status) before your current stay expires. I-539 extensions are rarely granted for B-2 visitors unless you have a compelling reason (serious illness, family emergency) and can show strong ties to your home country.

Student visas (F-1): duration of program plus grace period

An F-1 student visa permits you to stay for the duration of your academic program as listed on your Form I-20 (Certificate of may be able to access for Nonimmigrant Student Status), issued by your school. This might be 2 years for a master's degree or 4 years for an undergraduate degree. The I-20 is your actual authorization document; the visa in your passport is only the entry permit.

After your program ends, you receive a grace period of 60 days to prepare to leave the US or to change to another visa status. During this grace period, you cannot work (except in limited circumstances) and you cannot extend your stay. If you want to remain in the US after graduation, you must change to another visa category — such as H-1B (work visa) or F-2 (dependent) — before the grace period ends.

Your school's Designated School Official (DSO) monitors your status through the Student and Exchange Visitor Information System (SEVIS). If you fall out of status — by not enrolling in a full course load, by working off-campus without authorization, or by remaining after your grace period — you become deportable and must leave when ready or file for reinstatement, which is difficult and expensive.

Work visas: stay tied to petition validity

Work visas such as H-1B, L-1, O-1, and E-2 do not have a fixed duration printed on the visa itself. Instead, your stay is authorized for the validity period of your employer's petition filed with US Citizenship and Immigration Services (USCIS). An H-1B petition, for example, is typically valid for 3 years and can be renewed for another 3 years, allowing a maximum stay of 6 years. An L-1 visa can be valid for up to 7 years depending on the visa subcategory.

Your employer must file a new petition before your current authorization expires if you want to continue working and staying in the US. If your employer does not file, or if USCIS denies the renewal, your status ends on the expiration date of your current petition. You then have a grace period (usually 10 to 60 days depending on visa type) to leave the US or change to another status.

Some work visas allow you to change employers, but only if the new employer files a petition on your behalf. During the time between jobs, you may fall out of status if you work without authorization or remain in the US without a valid petition. Check with an immigration attorney or your employer's HR department about the rules for your specific visa type.

Exchange visitor visas (J-1): program duration plus 30 days

A J-1 exchange visitor visa is issued to participants in US government-sponsored exchange programs such as au pair programs, internships, or academic exchanges. Your stay is authorized for the duration of your program as listed on your Form DS-2019 (Certificate of may be able to access for Exchange Visitor Status), issued by your program sponsor.

After your program ends, you receive a 30-day grace period to depart the US. Unlike F-1 students, J-1 visa holders cannot extend their stay or change to another status during the grace period in most cases. Some J-1 programs also impose a two-year home residency requirement, which means you must return to your home country and live there for 2 years before you can return to the US on most other visa types. Your program sponsor will inform you if this requirement applies to you.

What happens if you overstay

Overstaying your permitted departure date has serious consequences. If you remain in the US even one day past the date in your passport, you are considered to be in the country unlawfully. CBP can initiate removal (deportation) proceedings against you at any time.

If you accrue unlawful presence, you trigger automatic bars to re-entry. Overstaying for more than 180 days triggers a 3-year bar to returning to the US. Overstaying for more than 1 year triggers a 10-year bar. These bars explore even if you leave voluntarily; you cannot straightforward depart and return without consequences. Additionally, overstaying can affect your ability to sponsor family members for visas in the future and can make you ineligible for many visa categories.

If you realize you will overstay, contact an immigration attorney when ready. In some cases, you may be able to file for a change of status or an extension before your current status expires, which can prevent the accrual of unlawful presence. Waiting until after your status expires makes your options much more limited.

How to find your departure date

Your departure date is printed on the arrival/departure record (Form I-94) that was issued when you entered the US. If you arrived by air or sea, you received an electronic I-94; you can retrieve it at cbp.gov/i94 by entering your passport number and date of birth. If you arrived by land, you may have received a paper I-94 card; check your passport for a stamp showing your permitted stay duration.

Do not rely on memory or on what the officer told you verbally. Write down the exact date from your I-94 or passport stamp and set a reminder on your phone or calendar. If the date is unclear or if you cannot locate your I-94, contact the nearest USCIS office or a may have access to immigration attorney to confirm your status before your important date approaches.

Frequently Asked Questions

Can I stay longer if I get married to a US citizen?

Marriage to a US citizen does not automatically extend your stay or change your status. You must file Form I-485 (process to Register Permanent Residence or Adjust Status) to change to lawful permanent resident status. Until USCIS approves your process, you must continue to follow the departure date on your current visa. If you overstay while waiting for approval, you may trigger bars to re-entry even if your marriage petition is later approved.

What if I need to stay longer for medical reasons?

Medical emergencies do not automatically extend your stay. You must file Form I-539 (process to Extend/Change Nonimmigrant Status) before your current status expires. USCIS will consider a serious medical condition as a reason for extension, but approval is not may provide. File as soon as possible and include medical documentation from a licensed physician. Do not wait until your departure date is near.

Can I extend my stay if I find a job?

Finding a job does not extend a tourist or visitor visa. You must change to a work visa category such as H-1B or L-1, which requires your employer to file a petition with USCIS. This process takes weeks or months. You cannot work legally on a B-1/B-2 visa while waiting for the petition to be approved. Consult an immigration attorney about the timeline and whether you can remain in the US during the petition process.

What does "port of entry" mean on my I-94?

The port of entry is the airport, seaport, or land border crossing where you physically entered the US. It is listed on your I-94 for record-keeping purposes. It does not affect how long you can stay. Your departure date is what matters.

If I leave the US before my departure date, can I return on the same visa?

Yes, if your visa is still valid (not expired) and you have not overstayed. Leaving early does not cancel your visa or your ability to return. However, when you re-enter, the CBP officer will issue a new I-94 with a new departure date. That new date may be shorter or longer than your previous one, depending on the officer's assessment of your circumstances at the time of re-entry.
