How long you can stay on a US tourist visa

A US tourist visa (B-1/B-2) does not set a fixed length of stay. Instead, a US Customs and Border Protection officer decides how long you can remain when you arrive at the border or airport. Most tourists receive permission to stay for six months, though some receive 30 days, 60 days, or longer depending on the officer's assessment and your circumstances.

The visa itself — the stamp or document in your passport — is valid for up to 10 years (or 6 years for some nationalities). That validity period only controls how many times you can enter the US, not how long you can stay once you arrive. You need a valid visa to board a plane to the US, but the actual length of your stay is determined at the port of entry.

When you arrive, the officer will stamp your passport with an I-94 arrival/departure record. This stamp shows your permitted stay date — often written as "6 months" or a specific date like "6/15/2025". That date is what matters. You must leave by that date or you will be in the country unlawfully.

Key Takeaways

  • Your tourist visa validity (usually 10 years) and your permitted stay length (usually 6 months) are two separate things.
  • A US Customs and Border Protection officer decides your stay length when you enter, not before you travel.
  • Your I-94 stamp shows the date you must leave; overstaying that date makes you unlawful even if your visa is still valid.
  • You can request an extension before your stay expires, but you must file the request with USCIS while still in the US.
  • Leaving on time protects your ability to return; overstaying can result in a ban from re-entering for years.

What the I-94 stamp means and where to find it

The I-94 is a small stamp or notation in your passport that shows the date you must leave the US. It is placed in your passport by the officer at the airport, land border, or seaport when you arrive. Some travelers receive a paper I-94 card instead, though most modern entries result in a digital record.

You should check your I-94 when ready after clearing customs. If the date is wrong — for example, if you need to stay longer for a legitimate reason — you can ask the officer to correct it before you leave the inspection area. Once you have left that area, correcting it becomes much harder.

If you need to verify your I-94 later, you can look it up on the US Department of Homeland Security website using your passport number and date of birth. This is useful if you lose your passport or need proof of your permitted stay date for an employer or school.

Why different travelers receive different stay lengths

Officers consider several factors when deciding how long to permit your stay. These include the purpose of your visit (tourism, business, visiting family), how long you said you planned to stay, whether you have ties to your home country (employment, property, family), your travel history, and your financial ability to support yourself during your stay.

A traveler visiting family for two weeks might receive exactly two weeks. A tourist with a round-trip ticket for six months might receive six months. A business traveler attending a conference might receive 30 days. The officer has discretion, and their decision is final at the moment of entry.

You cannot appeal the officer's decision at that moment, though you can later request an extension through USCIS if circumstances change. Being honest about your plans and having documentation (hotel reservations, return tickets, invitation letters from family) can help you receive the length of stay you need.

Extending your stay before it expires

If you need to remain in the US longer than your I-94 date allows, you must file a request for an extension with USCIS (US Citizenship and Immigration Services) before your current stay expires. The form is Form I-539, process to Extend/Change Nonimmigrant Status.

You must file while you are still in the US and before your I-94 date passes. Filing the form does not automatically extend your stay — you are technically still required to leave on your I-94 date unless USCIS approves the extension. However, if you file before the date expires, you are usually permitted to remain while USCIS reviews your request.

Extensions are not may provide. USCIS will examine whether your reason for staying longer is legitimate and whether you still meet the requirements of a tourist visa holder (for example, that you are not working and have funds to support yourself). Processing typically takes several weeks to several months.

What happens if you overstay your I-94 date

Remaining in the US after your I-94 date is a serious violation. You become unlawfully present, which can trigger deportation proceedings and a ban on re-entering the US for years. Even one day of overstay can have consequences.

If you overstay, you may be detained by Immigration and Customs Enforcement (ICE) and placed in removal proceedings. If you are ordered removed, you will be deported and typically barred from returning for three years (if you overstayed more than 180 days) or ten years (if you overstayed more than one year). Some violations can result in a permanent bar.

Overstaying also affects future visa applications. Any future visa process — whether for tourism, work, or family sponsorship — will be reviewed with your overstay on record. You will likely be denied unless you can show exceptional circumstances.

Leaving the US and re-entering later

When you leave the US before your I-94 date, your stay ends. You do not need to formally notify anyone; your departure is recorded electronically when you exit through a port of entry (airport, land border, or seaport).

You can return to the US on a new tourist visa as many times as you wish, as long as your visa is still valid and you meet entry requirements. Each entry gives you a new I-94 with a new permitted stay date. However, if you have a pattern of entering and staying for the maximum time allowed, officers may become suspicious that you are trying to live in the US on tourist visas rather than genuinely visiting, and they may grant shorter stays or deny entry.

If your visa has expired, you will need to obtain a new one before you can return. You cannot board a plane to the US without a valid visa in your passport, even if you have never overstayed before.

Frequently Asked Questions

Can I stay longer than six months on a tourist visa?

You can stay longer only if USCIS approves an extension before your current I-94 date expires. You must file Form I-539 while still in the US. Extensions are not automatic and depend on your circumstances. Most tourists do not receive extensions.

What if I lose my passport with my I-94 stamp?

You can look up your I-94 online using the DHS website, or contact USCIS to request a copy. You should also report the lost passport to your country's embassy. You will need proof of your permitted stay date if you are questioned by immigration authorities.

Do I need to leave exactly on my I-94 date or can I leave early?

You can leave any time before your I-94 date. Leaving early does not cause problems. Your stay ends when you depart, and you can return on a new visa whenever you wish, as long as your visa is still valid.

Can I work while on a tourist visa?

No. A B-1/B-2 tourist visa does not permit employment in the US. Working while on a tourist visa is a violation that can result in deportation and a ban on future entry. If you need to work in the US, you must obtain a work visa before you arrive.

What happens if I am denied entry at the border?

If an officer denies you entry, you will not receive an I-94 and will not be permitted to enter the US. You will be sent back to your country of origin. You can attempt to enter again later with a new visa, but the denial will be on your record and may affect future applications.
