You may petition your brother. However, after petitioning, a visa number has to be issued permitting him to legalize status which currently seems to take about 10-12 years from the date of filing petition. However, if that is the only means by which your brother could be sponsored then I recommend you file the petition and should other options become available then he may pursue those options as well.
