As a US Citizen you can apply for your brother's green card. The process takes about 12 years and he CANNOT stay in the US while he waits. The long wait is because there is a limit of 65,000 sibling green cards per year but there are so many people petitioning their siblings that there are about 700,000 people waiting for a green card, making the wait 10+ years. Hope that helps and good luck.
