My I-134 sponsor noticed that his tax return transcripts from the IRS include only the last 4 digits of his SSN. Also, form I-134 does not ask for SSN at all. I want to include additional income proof, like his 2024 W-2. The W-2 has his full SSN. He wants to redact (black-out) the first 5 digits of his SSN on the W-2 (leaving only the last 4 digits just like the tax transcripts) -- is this kind of redaction ok for USCIS?
