Yes, your US citizen brother can file for you. He must file a Form I-130 petition under F4 [brother/sister] of a US citizen. However, I must warn you in that category, his petition will take at least 12 years to become current. In other words, because visas are oversubscribed in the F4 category, do not expect to receive a green card for at least another 13 years or so. While the DACA provides a temporary respite from fear of removal it is temporary and hence, you should consider any and all other options that may be availing to you.
