I am a US citizen and I want to petition for my brother how long will it take

Currently in the month of July, immigrant visa availability is only open to those who filed I-130 petitions under the F-4 category for siblings of US citizens before February 8, 2007, except for natives of India, Mexico, and the Philippines who face longer wait times. So currently for your brother, the waiting time looks like approximately 14 years. If your brother has other ways to immigrate, he should explore those options. Your petition for him should be used as a backup only.
