He will need your birth certificate as you are the petitioner

James L. Arrasmith · Answer

For your father's family-based immigration interview, he will generally be required to present documents that directly pertain to his own application. This typically includes his birth certificate, marriage certificate (if applicable), police clearance, medical examination results, and evidence of his relationship to the petitioner, which in this case, is you.  
 
Your brother's birth certificate would not usually be necessary unless specifically requested by the consular officer, which could occur if they need to verify family composition or other details pertinent to the case. It's advisable to review the instructions provided by the National Visa Center (NVC) and the Embassy in Abu Dhabi, as they list the documents required for the interview. If additional documentation is necessary, the Embassy will provide that instruction. Your father should bring all documents that he believes are relevant and could support his application, but focus should be on the documents requested in the official correspondence from the Embassy or NVC.
