If your under daca, and your brother is a citizen, do you have to leave the country to be able to obtain the green card, if you weren’t brought over?

You probably need another plan since a sibling petition takes approximately 12 years to turn into a green card. There are probably other quicker ways to immigrate, e.g. marriage, employment sponsorship. In addition, persons here in the country who are being sponsored as siblings under the F4 category must ultimately leave the US for consular processing to obtain permanent residence if they are not legal. DACA is not considered a legal nonimmigrant status. The difficulty is that you would be under a 10 year bar for having stayed in the US unlawfully for one year or more if you left the country.
