Note on Filing Fee (Exceptions):

There are two exceptions:

  • The fee is $550 if filing for an adopted child.
  • There is no fee if filing for a member or veteran of the U.S. Armed Forces - proof of service required. However, the fee for a child of a veteran or member of the U.S. Armed Forces is the normal $600 fee ($550 if child is adopted).

To ensure your application is accepted, please ensure that you:

  • Check only 1 box in Part 1, Information about Your Eligibility. If you check more than one box, we will return your application for correction.
  • Pay the correct fee.
  • Sign your application in Part 7. A parent completing Form N-600 on behalf of a child younger than 14 years of age can sign in Part 7. If someone prepared the form for you (such as an attorney), they must sign in Part 8.
  • Submit required photos: See the Form N-600 instructions for information.

Attorney or representative:

You may be represented, at no expense to the U.S. Government, by an attorney or other duly authorized representative. Your representative must submit Form G-28, Notice of Entry or Appearance as Attorney or Representative, with your Form N-300. Your representative may also submit Form G-28 at the time of your interview.
