Form G-1566 Guide

USCIS evaluates the completeness of the request, the validity of signatures, and the accuracy of supporting documents. A common mismatch occurs when the proof of death is not provided for subjects born less than 100 years ago.

• Gather proof of death if the subject is deceased and born less than 100 years ago.
• Collect marriage certificates if applicable to support the request.
• Ensure all documents are legible and properly certified if translations are needed.
• Review the subject's information for accuracy to avoid mismatches.

• Missing required supporting documents, such as proof of death or marriage certificates.
• Invalid signature on the form, which can lead to rejection of the request.
• Incomplete information about the subject of record, such as missing dates of birth or names.

• Evidence of current immigration status or admission/parole.

• Not using legible photocopies.
• Incorrectly filling out the subject of record's information.
• Neglecting to include a self-addressed, prepaid return envelope.

• Situation: An applicant is preparing G-1566 and must include all required evidence. Task: They submit a complete packet within a 30-day preparation window. Action: They compile identity records, eligibility evidence, and the filing fee before submitting. Result: The petition is accepted without a request for missing items.
• Situation: A filer is close to a deadline for G-1566. Task: They submit within the required 90-day timeline. Action: They finalize the packet and file within the stated window. Result: The case proceeds without a late-filing issue.
• Situation: A petitioner must reference a receipt number. Task: They match the receipt number to the underlying petition. Action: They include the exact receipt number on G-1566 and attach the notice copy. Result: USCIS can verify the underlying filing quickly.

• A stamped signature is acceptable; it is not. USCIS requires a handwritten signature on the form.
• Proof of death is always required; it is not if the subject was born 100 years ago or more. In such cases, proof of death is not necessary.
• You can submit original documents anytime; you should only submit originals if specifically requested. Submitting originals when not required can lead to their destruction.
• All documents must be originals; this is incorrect. Legible photocopies are acceptable unless the instructions specify otherwise.
