N-300 — Application to File Declaration of Intention

N-300 support helps a lawful permanent resident organize the information needed to declare an intention to become a U.S. citizen. USCIS does not require Form N-300 to become eligible for naturalization, so this path includes a review check before reviewed materials are made available.

What we help with

We collect identity, lawful permanent resident, residence, address, absence, interpreter/preparer, signature, and additional-information details in plain language.

Review before materials are ready

A Human Review Specialist checks whether N-300 is appropriate, confirms current USCIS edition and fee, and reviews missing evidence or risk flags before reviewed materials are ready.

You review, print, sign

You review every page, print and sign where required, and decide whether and when to submit. Immigration Oasis does not automatically file with USCIS.

Important: Immigration Oasis is not USCIS, not the government, and not a law firm. USCIS forms are free. Government filing fees are separate. Form N-300 Edition 04/01/24 was used for this support path. G-1055 Edition 05/29/26 shows general filing at $320, with possible fee-waiver eligibility for certain applicants. Current USCIS.gov edition, fee, filing route, and instructions must be confirmed before reviewed materials are made available.

Review checks before materials are ready

  • Confirm whether you are a lawful permanent resident over 18 and currently residing in the United States pursuant to lawful admission for permanent residence.
  • Confirm N-300 is actually useful for the user because USCIS does not require N-300 to become eligible for naturalization.
  • Confirm current USCIS edition, G-1055 fee, fee-waiver posture, filing route, evidence, and signatures before reviewed materials are made available.
  • Keep reviewed materials on hold until required review is complete; no automatic USCIS filing, no legal advice, and no outcome guarantee.
