Where to File

You have two options for filing your Form N-600 with USCIS:

  • Online, using an electronic application form; or
  • By mail, using a paper application form.

1. Filing your Form N-600 online

If you are applying from outside the U.S., are applying for a fee waiver, or are a member or veteran of any branch of the U.S. military filing on your own behalf, you cannot currently file your Form N-600 online. Please see section 2 below for how to file your form by mail.

You must create an online account to file your Form N-600 online. Through your online account, you can:

  • Check the status of your case;
  • Receive notifications and case updates;
  • Respond to requests for evidence; and
  • Manage your contact information, including updating your address.

Attorneys and accredited representatives can also create an online account, which will allow them to manage all of their clients’ applications in one place.

2.  Filing your Form N-600 by mail

If you file on paper, are a member or veteran of any branch of the U.S. military filing on your own behalf, or are applying for a fee waiver, you must mail your application to USCIS using one of the listed mailing addresses:

Filing Fee

$1,170. (This fee applies even if you are filing as an adopted child or as a child of a veteran or member of the U.S. armed forces.) 

You may pay the fee with a money order, personal check, or cashier’s check.  When filing at a USCIS Lockbox facility, you may also pay by credit card using Form G-1450, Authorization for Credit Card Transactions. If you pay by check, you must make your check payable to the U.S. Department of Homeland Security. Please note that service centers are not able to process credit card payments. 

When you send a payment, you agree to pay for a government service. Filing and biometric service fees are final and non-refundable, regardless of any action we take on your application, petition, or request, or if you withdraw your request. Use our Fee Calculator to help determine your fee.

Note:  There is no fee if you are a member or veteran of the U.S. armed forces, but you must submit proof of service.

Read our Paying Immigration Fees page for information on how to pay the fee.
