Question about presence proof

Hello,
I am doing my brother DACA and he's been here since 2 years old and he got out of HS on 08 After HS he didn't work or anything he depended on my parents till 2011 he went to college and still in college. What kind of proof i would need to send from 08-2011? He doesn't have bank/credit etc. All he has is just soccer credentials for those years.

Credentials will be helpful. But if he was depending on your parents then maybe your parents taxes. Any medical bill anything with his name is helpful

Anything with his name and date. and I mean everything with those two things. Let me guess, he didn't make facebook posts either during that time right? Facebook posts miraculously count

Receipts from college applications or whatever he did in prep for college, cell phone bills, gym memberships, if he played in any sports teams or volunteered anywhere, Costco cards, internet purchases, baptized anyone, traffic tickets, a rental lease that has him as someone who is living in the home, etc. If you have gaps include two notarized affidavits from citizens/permanent residents who have direct knowledge that he was living in the United States from 2008-2011. Have them be specific as to how they know he was living here. i.e. "He's my next door neighbor so I saw him just about every day during 2008-2010." "He's my best friend so I saw him about once a week during the period of 2008-2011" and list specific dates and examples when possible. 3 years is a big gap so I would try to find at least a few things during that time instead of relying only on the affidavits for the full period though.

Try facebook posts with locations on them. I actually used some of my flickr photos too, as secondary evidences.

And I agree, definitely internet purchases, say ebay or amazon receipts
