I recently received RFE for my 485 due to names not matching in my passport and in my birth certificate. I had originally submitted an affidavit that both the names represent me but USCIS didn't accept it. The RFE is,
"Failure to submit sufficient evidence of your name as listed on the Form I-485 will result in your documents reflecting the name as listed on your birth certificate/document. Copied of the personal pages in your passport OR affidavits are not sufficient to establish a legal name change. Court documents submitted as evidence of name change must have been registered with the proper civil authority."
Could anyone suggest what documents i need to provide ?
