On July 10, 2026, U.S. Citizenship and Immigration Services (USCIS) issued Policy Alert 2026-03, updating its Policy Manual consistent with the interim final rule (IFR) amending USCIS signature regulations which became effective the same day.
For applications filed on or after July 10, 2026, other than Forms N-600 and N-600K, USCIS may assess signature validity at any point in processing. If USCIS accepts a filing and later determines the signature is invalid, the adjudicator may:
Reject the filing and return the fee, particularly where the deficiency is identified early and before significant adjudicative resources are spent; or
Deny the benefit request, retain the filing fee, and treat the application as fully adjudicated.
