I-94 Permit: When You Need It, How Much It Costs and How to Apply

By the deGaritas Online editorial team · Updated Friday, October 30, 2026 · 2 min read

In short: You need the I-94 if you go beyond the border zone or will stay longer than 30 days. You can apply online up to 7 days in advance or at the border crossing, and it costs about 30 dollars.

What is the I-94?

It is the arrival and departure record that CBP issues to visitors. It is not a permit for your car: it is a personal immigration document. It shows the date until which you can remain in the United States.

When do I need it?

With a B1/B2 visa or Border Crossing Card you do not need an I-94 if you stay within the border zone and for less than 30 days. That zone is:

  • California and Texas: 25 miles (about 40 km) from the border.
  • New Mexico: 55 miles (about 88 km).
  • Arizona: 75 miles (about 120 km), which includes Tucson.

If you go farther (Los Angeles, Phoenix, San Antonio, Houston) or will stay longer than 30 days, you need the I-94.

How to apply

  1. Go to CBP's official I-94 website or use the CBP One app.
  2. Enter your personal, passport and visa details, and pay online. You can do it up to 7 days before crossing.
  3. When you arrive at the border crossing, go to the inspection office so the officer can activate it with your fingerprints and photo.

You can also apply directly at the border crossing, but it usually takes longer. The fee is around 30 dollars per person; check the current amount on the official website before paying.

How long does it last?

It normally allows stays of up to six months, depending on what the officer authorizes, and is valid for multiple entries while it remains valid. Check the expiration date on your record and leave before that date.

Common mistakes

  • Thinking the I-94 is for the car: it is for you.
  • Traveling beyond the border zone without it: it can cost you your visa.
  • Not leaving before the deadline: overstaying can void your visa.

Also check the documents to cross and car insurance.

Frequently asked questions

Do I need an I-94 to go to San Diego?

No, if you are only going to San Diego and return within 30 days: it is inside the California border zone.

Do I need an I-94 to go to Tucson?

No. In Arizona the border zone extends 75 miles, which includes Tucson.

Can I apply for the I-94 online?

Yes, on CBP's official website or in the CBP One app, up to 7 days before crossing. When you arrive you must see the officer to activate it.
