If you have received your immigrant visa from the United States Department of State, you are required to pay $220 to United States Citizenship and Immigration Services (USCIS).
HomeUS Visa & ImmigrationHow To Find Your Immigrant Case Number?

The United States Citizenship and Immigration Services (USCIS) Immigrant fee pays for the expenses incurred in processing, maintaining, and filing your immigrant visa package as well as issuing documents, such as your permanent residency card (or Green Card).

While you may pay the fee after arriving in the U.S., the best way to pay the fee is after receiving your visa package from the Department of State and before traveling to the U.S. 

You will not be issued a Green Card until you have paid the USCIS immigrant fee. You must pay the fee online using the USCIS Electronic Immigration System.

However, you’ll need your Department of State (DOS) Case ID and Alien Registration Number (A-number) to pay the fee. If you are paying on someone else’s behalf, such as a friend or member of your family, you will also need their A-number and DOS Case ID.

You will learn what an A-Number is, what a DOS Case ID is, where to find one and how to track your application status online from this article.

What Is A-Number?

Your Alien Registration Number is known as your A-Number. It’s represented by the letter “A” followed by 8 or 9 numbers. For example, A012345678.

What Is A DOS Case ID?

Your Department of State (DOS) Case ID is your DOS Case ID. Your DOS Case ID is made up of three letters and is followed by 9 or 10 numbers. For example, ABC123456789. 

If you are an immigrant on a Diversity Visa, your DOS Case ID will have 4 numbers followed by 2 letters and 5 more numbers. For example, 0000AB12345.

How To Find Your A-Number And Your DOS Case ID?

Your A-Number and DOS case ID can be found on the Immigrant Data Summary, the USCIS Immigrant Fee handout, or the Immigrant Visa Stamp.

The DOS interviewing officer should have handed you a USCIS Immigrant Fee Handout when you showed up for your interview at the U.S. embassy or consulate. This document gives you instructions on how to pay your USCIS immigration fees. 

Your A-number and DOS Case ID can be found in the upper right corner of your USCIS Immigrant Fee Handout.

Remember to make a copy of your USCIS Immigrant Fee handout or write down your A-Number and DOS Case ID and keep it in a safe place.

If you did not get an immigrant data summary or a USCIS Immigrant Fee Handout with your visa packet, please get in touch with the U.S. Embassy or Consulate that issued your visa.

Your A-Number and DOS Case ID can also be found on your visa stamp (also referred to as your visa foil) in your passport if you don’t have your Immigrant Data Summary or USCIS Immigrant Fee Handout on hand.

On your visa stamp, your A-Number is listed as the Registration Number. Add a zero after the “A” and before the first digit if your A-Number is less than 9 digits to make it a 9-digit number. A12345678, for example, would become “A012345678.”

The IV Case Number on your visa stamp corresponds to your DOS Case ID. The IV Case Number contains two additional numbers at the end, such as 01 or 02. 

Do not enter the last two numbers as your DOS Case ID when entering the IV Case Number. Your DOS Case ID would be “ABV12345678” (without the “01”) if your IV Case Number was “ABC1234567801”.

Schedule A Meeting With Your Local USCIS Office

If you’re still having trouble locating your A-Number and your DOS Case ID, you can make an InfoPass appointment to go to your nearby USCIS office, where an immigration services official can provide you with the information.
