What is an Arrival-Departure Document and Why Do I Need One?

A USCIS Form I-94 (Arrival-Departure Record) or Form I-95 (Crewman's Landing Permit) shows the date you arrived in the United States and the "Admitted Until" date, the date when your authorized period of stay expires. You will receive an USCIS Form I-94 or I-95 from an USCIS inspector when arriving in the United States at a land border port-of-entry or from an airline or ship representative when arriving at an air or sea port-of-entry by aircraft or ship. The form must be completed and presented to an USCIS inspector who may ask you questions about the purpose of your trip, how long you will be in the United States, and your residence abroad. Do not lose this form. When you leave the country, you should give the USCIS Form I-94 or I-95 to your airline or ship representative, or, if you are departing over a land border, give it to a Mexican or Canadian immigration inspector. An USCIS Form I-94 or I-95 that has been approved by an USCIS inspector can prove that you arrived in the country legally and that you have not stayed beyond the period of stay authorized. In addition, turning in USCIS Form I-94 or I-95 to the proper authorities when you leave the country can prove that you did not violate U.S. laws by staying in the country too long. Proof that you are willing to obey U.S. immigration laws will be very important if you again want to travel to the U.S. as an immigrant or nonimmigrant in the future.

If you are applying for an extension of stay or change of status, you will also need to be issued an USCIS Form I-94 or I-95 if you were not issued one of these documents when you entered the country.

Canadians who travel to the United States as tourists or on business generally do not need an USCIS Form I-94. Also, certain Mexicans who have a nonresident alien Mexican border crossing card (commonly known as a laser visa), or a multiple-entry nonimmigrant visa may not need an USCIS Form I-94.

If your USCIS Form I-94 (Arrival - Departure Record) or USCIS Form I-95 (Crewman's Landing Permit) is lost, stolen, or mutilated, you must replace it.

I Need a New One - How Do I Apply?

To replace a lost, stolen, or mutilated USCIS Form I-94 (Arrival-Departure Record) or Form I-95 (Crewman's Landing Permit), you must file USCIS Form I-102 (Application for Replacement/Initial Nonimmigrant Arrival - Departure Document). If the USCIS Form I-94 or Form I-95 is mutilated, attach the original form. If the USCIS Form I-94 or USCIS Form I-95 was lost or stolen, a copy of the original USCIS Form I-94. If you do not have a copy of your original USCIS Form I-94, a copy of the biographic/photo page from your passport and a copy of the passport page that was stamped by immigration inspectors when you entered the country. If you cannot any evidence of your legal admission to the United States, a full explanation and proof of your identity.

If you are applying to extend your stay in the United States or change your immigration status, you will be asked to give USCIS your Form I-94. If you were not given an USCIS Form I-94 when you were legally admitted to the United States, file USCIS Form I-102. You will need to give USCIS proof that you were legally admitted to the United States. You should file USCIS Form I-102 at the same time that you apply to extend your stay in the United States or change your immigration status.

Forms are available online, or by calling 1-800-870-3676, or by ting an online request to receive forms by mail. After receiving Form I-102, read it carefully and note the documentation that must be ted. Detailed information is provided in the accompanying instructions for Form I-102.
